Bug Description

Binary package hint: hal

When I upgraded the kernel on my System76 Gazelle (basically a ASUS Z62FP without the Microsoft tax) from 2.6.17 to 2.6.20, the hard disk began freezing for 30 seconds every few minutes whenever the CD/DVD drive was empty. When there is a disk in the optical drive, the freezes occur much less often, but I'm sure there's been at least one even with a CD in.

The relevant part of the dmesg is:

I'm filing this bug against HAL because kernel developer Tejun Heo says HAL is poking the CD/DVD drive and confusing it, and indeed when I kill hald the problem goes away. On the other hand, I only noticed the problem after upgrading the kernel, and when I force the old ide_generic driver to be used by blacklisting ata_piix, the problem also goes away, so maybe it should be filed against the kernel package instead.

dmesg and lspci -vvx attached

I tried running hald in verbose mode with "hald --daemon=yes --verbose=yes --use-syslog", but no messages from hald appear in /var/log/syslog at the same time as the freeze. There are plenty of messages when hald starts up, but then it's silent when the freeze actually happens.

Here's the output of "lshal" though, that might be useful.

Hi,
there's a process hald-addon-storage which, surprise, polls removable media. You can try to kill the one associated with your CD/DVD drive. But as you said it's surely a kernel bug and hald only triggers it.

My problem began after a Feisty update as well.

Try booting into recovery mode and running e2fsck on each partition.
Then add the kernel options acpi=off pci=bios That seems to have got my
system working again. I did some tests last night and could boot with
acpi=off but without the option I had problems. I have also noticed some
hard disk corruption now as well. The same disk worked with no problems
when I booted using an old knoppix disk. So I conclude there is a
problem somewhere between the libata driver and the hardware.

Ran some tests last night:

1. Adding acpi=off as a boot parameter appears to make the system more stable. I tried various bios and kernel parameter options but the best combination was leaving the bios in all default settings and adding the acpi=off to the kernel. This could be a red herring as the problem seems to be intermittent anyway.

2. I only get problems with a 250GB Maxtor maxline iii drive. An 80Gb Samsung Spinpoint works with no issues.

3. Booting the system from an old Knoppix disk I got no issues. The issue appears to lie with how recent kernels interact with the maxline disk.

4. I am seeing some corruption and had to e2fsck my root partition.

I'd like to add a nice little me too to this bug. I have a system76 gazelle as well. I can say that 2.6.20-11-generic worked fine, while -12 and -13 exhibit the behavior above. Though I believe -11 uses the older non-libata driver. For now I have -11 set to be my primary kernel and I boot into the latest whenever I see an update to check if its fixed.

I also tried the cd in drive thing and it seemed to work for me. Once I took the cd out I got a freeze within a few minutes.

Here are steps to workaround the problem during the installation process:

  1. Add break=top to the kernel cmdline
  2. At the prompt, run: modprobe piix
  3. Then exit

And, here steps to make the workaround permanent after an installation:

  echo blacklist ata_piix | sudo tee -a /etc/modprobe.d/blacklist-ata
  echo piix | sudo tee -a /etc/initramfs-tools/modules
  sudo update-initramfs -u
  sudo reboot

The problem should be fixed for the first SRU release of Feisty.

What does it mean "during the installation process"? Do I have to boot from the live cd? and follow the first three steps?

And what about the remaining four steps? when do I have to follow them?

Thanks for the patience

Carl, I did pretty much the same thing on my existing installation and it works fine. It's just using the old piix driver instead of the new ata-piix driver. What's supposed to be the problem?

As I posted here http://ubuntuforums.org/showthread.php?t=598580, feisty kernel under gutsy + blacklisting some modules is a way to solve this problem, although this causes problems with usb devices (i.e. I can't mount camera anymore although feisty could do it with no problems) and cpu scaling.
I guess we'd need a new gutsy kernel or a customized one.

A few more notes from testing. A lot of people talking about CD-ROM drives. I have two optical drives, one Samsung and one NEC.

I disconnected the Samsung drive - same problem.

Connect both optical drives plus Samsung SATA harddrive - problem

Connect both optical drives plus Maxtor SATA harddrive - problem

Disconnect SATA hardrive - no problem

From what I can tell the issue is with the SATA harddrive and not with any of the optical drives. Currently I am using the system everyday with both optical drives and an IDE hard drive with no problems. As soon as I reconnect the SATA hard drive - problems.

The SATA harddrive has been used before in a Ubuntu box with no problems - these issues developed sometime around an upgrade to Feisty. Currently I am using Gutsy with exactly the same problems.

Another point - the piix workaround doesn't seem to be the key to the issue - I have a via board and I get the problem.

The problem is solved on my machine - I replaced the SATA cabling with better quality Akasa latch cables instead of the cheap cables that come with the motherboards. So far I have installed and run Ubuntu/Hardy and installed Gentoo (on another partition) and compiled X/Gnome with no problems. The machine has been rebooted several times and has not frozen once.

So I can confirm that one possible cause of the error -

[ 231.478375] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen

Could be poor quality cabling.

I've read through this and countless other posts about this issue (which I am also experiencing). It truly does render the computer useless.

The only big thing that jumps out at me in this thread is that everyone is mentioning problems with their CD/DVD drives, and upgrading firmware, etc. So... I don't even HAVE an optical drive installed on the system, and this problem happens every time I boot.

I do have an Intel chipset, and I was thinking I'd try blacklisting the ata piix module, but currently I am remote (over ssh), and the computer takes several minutes to respond even to shell commands. So I'd venture to say this isn't only a problem with optical drives. All I have is 3 internal SATA drives. No external USB, no optical, no floppy. I also tried stopping the HAL daemon, and initially it seemed JUST A LITTLE better, although the messages still show up in the syslog. I don't know if I should try to blacklist ata piix while I'm remote, as I've noticed in reading through posts that it might render the machine unbootable.

Anything else I can try? This is running Intrepid with all recent updates, 3 internal SATA drives, two of which are using mdadm for 3 RAID1 partitions and 1 RAID0 partition. And I've done countless diagnostics and all hardware appears normal. Also, I've removed the third (non-RAID) drive and the problem still happens. errors:

So it would appear that this is, in fact a hardware issue (at least in my case). Like I said, my mem, mobo, proc, and HDD's all were good. The one thing I never considered: power supply.

It would appear that one of my drives was consistently receiving too little power. It just occured to me out of the blue when I was sitting there dealing with this problem and heard what I thought were my fans spinning down, then back up again, within 2 seconds.

I had been using a splitter that splits one Molex 4-pin adapter into 2 SATA power adapter. I changed the wire configurations around so that each 4-pin Molex was only allocated one HDD per. Since then I show 2 days of system uptime with no recurrence of this problem.

I've since ordered a new power supply, as this one is most certainly about to die.

Thanks for the responses, everyone. Sorry to waste time and effort!

Same probleme and I had to wait a long time to find a solution : flashing the firmware of my latop cdrom.

I've got an ACER Aspire 9410, the cdrom is a TSSTCorp TS-L632D
And acer only deliver 1 firmware : AC01

As stated on the other post, crossing flashing is okay, I've flashed witch :" SC04 - Original Samsung Computer Firmware "
And all my probleme goes away

a source to find firmwares : http://backfire.rpc1.org/tsstcorp/index.php?path=TS-L632D/

PS : to crossflash I've done it under windows with the binary suplied "sfdnwin " and the option "-nocheck"
