ata1.00: exception Emask 0x0 SAct 0x807f SErr 0x0 action 0x6 frozen

[Marcel]

Binary package hint: linux-headers-2.6.27-7-generic

Since I'm running 8.10 alpha6 64-bit, I'm having now and then a frozen machine for 1 or more minutes.
Although I can not pinpoint the reason, it seems to happen soon after booting and round the whole hour.
I guess there is some process in the background responsible. So I include the entries of the system log from the freezes at 12:00 and 14:00.

I'm not sure if I file this issue under the right package. Sorry for that.

This seems to be similar to my problem.

Hi Marcel,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/karmic .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 285892

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Thanks gab0r,
I didn' notice the issue happens after standby, I use it very often and didn't relate the issue to the standby.
Now I always shutdown and the freeze don't happen any more. System is now usable, but without standby :(((((

[Graham (graham-g-lambert)]

I have had the same problem on Ubuntu karmic and Suse 11.1. Both installations went well (apart for the fact the GRUB overwrites the disk area used by the RAID on my system in both cases - this is solved by removing stage1_5 from the GRUB installation directory - rename/move or delete the file).

After a successful install both systems started without error and fairly fast. However, after downloading the 'recent updates' (could be irrelevant - see later) that are applied after installation, the system(s) started with the above error "device reported invalid CHS sector 0". Initially this is attempted at UDMA/100 and then the bus is gradually degraded through UDMA/66 and UDMA/33, until finally the disk connection is run at the slowest speed. This takes just under 10 minutes to complete on my system, and I guess would explain the slow startup behaviour experienced by users of other systems as described above. After this the system runs very raggedly - not as smooth as I am used to with various Linux installations. I assume that the bus connection is kept at the lowest speed and the swap partition does not allow fast paging.

One might think that this is a hardware fault but so many people reporting the same error, here and on other forums, that something tells me this is a software fault... and as it happens on more than one Linux release, it is not system specific, but likely to be linked to the GRUB bootloader itself.

The 'standby' issue raised above and not the updates might give a clue. From what I can perceive, GRUB attempts to 'resume' the system from the data stored on the swap partition when the system shuts down. If the swap partition cannot be read as expected during startup then I expect that we would see an error. Removing or commenting out the option 'resume=/dev/swap' from the grub installation file in /boot/grub/menu.lst should solve this.

I am not in a position to try this immediately but would be interested in any comments. I intend to check this myself in a couple of days.

I did not notice your request before, but this bug is not an issue for me anymore.
On 2008-11-03, I reinstalled 8.10 without AHCI enabled in the bios and I did not encounter any freezes.

At this moment I'm running Karmic with 2.6.31-16-generic, still with AHCI disabled in the bios.
(The only, possible related, problem since Karmic is the inability to auto-mount all partitions after a hard reset.)

[giorgio_fornara (giorgio-fornara)]

As a supplementary infoo the asus A8J bios don't have AHCI option.
This could be a solution for someone... not yet a solution of the bug.
Any one found different solutions?

[javi (javuchi)]

Attention: a not simple workaround has been found for some of us (specially Samsung hard disk/bios users), look at this link:

http://wiki.archlinux.org/index.php/Samsung_N140

Please, kernel developers of Ubuntu, insert these workarounds in the next kernel version:

Here I copy the relevant parts:

---
Possible BIOS problem causes a SATA hardreset shortly after boot. This is unresolved up to Samsung N140 BIOS 04CU, and Samsung N130 BIOS 05CM, although a kernel patch is being investigated. See http://bugzilla.kernel.org/show_bug.cgi?id=14314, http://bugzilla.kernel.org/show_bug.cgi?id=13416, http://lkml.indiana.edu/hypermail/linux/kernel/0908.2/02809.html and http://lkml.indiana.edu/hypermail/linux/kernel/0911.3/01604.html .
A summary of the status as currently understood:
About 5 minutes after boot or resume, the BIOS switches on some power saving features which were not enabled at boot. It enables additional (sleepier) processor C-states, and sends power management instructions to the HDD. It does these behind the operating system's back -- not using ACPI, which would be handled correctly by Linux. Instead the sudden change results in a SATA exception at the first disk access following the switch. At that point the SATA driver resets the disk to resolve the problem. The result: the user sees a complete system freeze for about 30 seconds, after which operation of the machine continues normally. This can occur during the periodic fsck at boot if it is running at switch time. Either Samsung needs to be convinced to fix the BIOS, or the Linux kernel needs to be modified to behave more gracefully (Windows doesn't freeze noticeably if at all).
It has been reported that some OpenSUSE kernels [1] do not freeze and testing is progress in the Arch Forums. The patch libata-ata_piix-clear-spurious-IRQ has been reported to resolve the freezing problem. (Hint: to look at the rpm use rpmextract, and then untar config.tar.bz2 and patches.*.tar.bz2).
There is a kernel patch available which changes the backlight brightness using SMI instead of poking PCI config space. It provides a kernel module called "samsung-laptop". Interestingly a special (as yet unreleased?) BIOS for the N130 can be informed that the OS is Linux by a version of this patch which is included in OpenSUSE 11.1. The effect of this hasn't been published.
The N140 and N130 BIOSes have Phoenix FailSafe (you have been warned). It's not clear if the SATA problem has any relation to this.
Version 01CM of the N130 BIOS has been reported to not cause freezes, unlike all later ones which do.
This problem is hazardous for your filesystem so take precautions. For example use ext3 (not ext4) with option data=journal and install backup software.

errors in the logs. I noticed this because ivtv was outputting a ton of "Unable to Save MPG stream" errors. I thought it was a bug in ivtv but now I realize that it was a SATA 3 error and that the drive had become read-only.

this has happened a few times now and the system is locked up hard each time. It can ping but nothing is running. I had ssh access during one of these events and nothing worked (reboot, all process were in zombie state, etc.). which makes sense as the root drive was now read-only and inoperable.

I've lost data because of this as well. my entire /var/lib/mysql directory was blown away and recovered into lost+found. other directories are there as well.

I'm going to a) switch the sata 3 drive to the sata 2 controller, and b) reinstall ubuntu (as I'm not sure what went missing with the latest crash). I'm a little surprised that this bug has remained through multiple kernel revisions.

OK, so it's a TSSTcorp CDDVDW SH-S223C . Looks like a run of the mill

Btw, please stick to textual information in the future - it's much easier to deal with that way!

Interesting. So we basically get the information we request, it just takes a lot of time. What is logged to dmesg while doing this?

(Hmm, we really need better debugging infrastructure in ata_id - I'll try to write a patch for that.)

Jeff (or other kernel hackers with ATA expereince) : any idea what is going on here? Thanks

[Mesa (astewart-deactivatedaccount-deactivatedaccount-deactivatedaccount)]

Since upgrading to natty alpha about month ago the issue has more or less disappeared for me (see my comment earlier re problem in lucid and maverick) - previously used to get it every single boot (i.e. daily) plus intermittently on top - since upgrading only had the issue once.

Note that upgrading to an alpha release is a bad idea for most - wait for proper release unless you can live with the breakages.

Would be good to know if it's also now fixed for Raj B as he was running an earlier version of Natty than I.

[Chuck (chuck-redhat-bugs)]

I found this thread:
https://bbs.archlinux.org/viewtopic.php?pid=895404

which says that some devices may not support 16-byte ATA commands. For our kernel, you would disable them by adding "libata.atapi_passthru16=0" to the kernel boot options, though this is just a workaround.

Hi, it looks that this problem still exist in 2.6.38 kernel.

Hi, I also can confirm the problem, because I am experiencing it with Ubuntu 10.10 2.6.35-28-generic on Dell Latitude E6500. Dell's Diagnostic Tool reports no errors (I have checked it several times).

[Travis Ogdon (togdon)]

I'm still seeing the problem in the most recent build of Natty as well:

2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
ext4 / partition for the whole drive (minus a bit of swap)

This is on a new (to me) box that was happily running Windows 7 prior to me installing Natty Beta2.

Hopefully relevant hardware information:

SAMSUNG Spinpoint F1 HD753LJ 750GB hard drive.
Intel Core i7-920 processor
JMicron Technology Corp. JMB362/JMB363 Serial ATA Controller (rev 03)
nVidia Corporation G92 [GeForce 9800 GT] (rev a2) (with the proprietary driver installed)

It happens if I set the SATA controller either in IDE or AHCI mode in the BIOS.

I've also tried the vanilla mainline kernel (2.6.38-02063803-generic #201104150912 SMP Fri Apr 15 09:15:15 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.38.3-natty/) and had the same failures.

Here's the error that I see:

What's odd is that the box seemed ok until I started copying my data over to it, now it's essentially unusable.

I can consistently lock up the drive by running a SMART scan on it (smartctl --test=short /dev/sda), so if someone needs a way to consistently repeat the error, there you go.

It's still present in Oneiric with all kernels up to and including 3.0.0-14-generic.

Symptom : System very often boots either while starting a KDE or Gnome session (right after bootup), or when waking up from resume. The lock corresponds to a steady lit HD LED and entries looking very much like previous comment's.

[Jeff (jeff-redhat-bugs)]

Reassigning to kernel pkg, as this appears to be a kernel problem.

TSSTcorp devices have special workarounds in the kernel. In ata_device_blacklist[] we see

        /* Maybe we should just blacklist TSSTcorp... */
        { "TSSTcorp CDDVDW SH-S202[HJN]", "SB0[01]", ATA_HORKAGE_IVB, },

It is worth attempting to emulate what the above workaround attempts to accomplish with ATA_HORKAGE_IVB, which is to force the cable type.

Kernel module "libata" accepts the "force" module parameter.

Try setting libata.force=40c to force a 40c cable type.

[Miro (miro-redhat-bugs)]

Hello,

I was able to solve this issue on my configuration so I hope this will help somebody. Recently I have migrated my CentOS 6.3 server from Intel based motherboard Gigabyte GA-P55-UD3L (rev. 1.0) to AMD based motherboard MSI 790FX-GD70. The only change in the system was the motherboard, cpu and memory, the rest of the configuration stayed the same. Immediately after migration I have started experiencing this exact issue

During boot I was getting errors

Nov 17 23:41:12 storage kernel: ata6.00: qc timeout (cmd 0xec)

[Fedora (fedora-redhat-bugs)]

This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '16'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 16 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" and open it against that version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

[Antoine (antoine-redhat-bugs)]

FWIW: I've moved this cdrom device to another SATA port on the motherboard so that I could then change the configuration in the BIOS for this port to not use AHCI and the problem has gone.

[Fedora (fedora-redhat-bugs)]

Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
