Bug Description

At bootup I end up in busybox and I see the following message on the top of the screen "Gave up waiting for root device"
Actually I think that my hard drive "falls asleep" just after leaving grub. When I'm in the busybox I need to unplug my hard drive (serial ata) and to plug it again so that I can hear that it's restarting. After doing that I type exit in the busybox and the boot process restarts normally.
Dmesg shows me that:

[ 9.672007] ata3: link is slow to respond, please be patient (ready=0)
[ 14.320007] ata3: COMRESET failed (errno=-16)
[ 19.680006] ata3: link is slow to respond, please be patient (ready=0)
[ 24.328007] ata3: COMRESET failed (errno=-16)
[ 29.688007] ata3: link is slow to respond, please be patient (ready=0)
[ 59.092004] ata3: COMRESET failed (errno=-16)
[ 59.092004] ata3: limiting SATA link speed to 1.5 Gbps
[ 59.688009] ata3: SATA link down (SStatus 0 SControl 310)
[ 60.164017] ata4: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 60.196367] ata4.00: HPA detected: current 160834367, native 160836480
[ 60.196371] ata4.00: ATA-6: HDS722580VLSA80, V32OA6MA, max UDMA/100
[ 60.196373] ata4.00: 160834367 sectors, multi 16: LBA48

The COMRESET thing continues as far as I don't unplug and plug again my hard drive.

I'm not sure this bug concerns only Ubuntu because I tried recently other distributions with the same kernel and I get the same error (Debian and pmagic liveCD) So I think this bug is concerning the kernel 2.6.26 but I don't know how to report this bug upstream.
I also have to tell you that it's a SATA II hard drive (3gbps) on a (nforce 3) SATA I controller (1.5gbps). And it appears that the controller does not fully support the hard drive (or the SATA I retro-compatibility of the hard drive is malfunctioning I don't know) But with older kernel it did always work without any problem.

I'm running intrepid ibex up-to-date, kernel 2.6.26-5-generic
Please tell me if I should attach the entire dmesg or anything.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at . I have classified this bug as a bug in linux.
For future reference you might be interested to know that a lot of applications have bug reporting functionality built in to them. This can be accessed via the Report a Problem option in the Help menu for the application with which you are having an issue. You can learn more about this feature at

Please include the following additional information, if you have not already done so (pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.


2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

From the upstream bug report, it looks like a patch has been isolated and making it's way into the mainline kernel. I'm reassigning this to the kernel team to try to get this patch merged prior to Intrepid's final release. Thanks.

From my understanding, this was fixed by commit 2fd673ecf0378ddeeeb87b3605e50212e0c0ddc6 and is now in the latest Intrepid kernel. Can you retest this for me and let me know if it has resolved the problem?

I did a fresh install of intrepid beta today with kernel 2.6.27-4 and everything was working fine.
But when I upgraded to kernel 2.6.27-7 I had again the bug described above though the fix was released and worked until now.
Here's the dmesg with kernel 2.6.27-7. I will test now if this happens with 2.6.27-6 that is still in the repo.

I can confirm the above posts. I tried both the stock kernel in Intrepid as well as the server version. Problem occurred prior to patch in 2.6.27-4 and then reverted and has occurred in all kernel releases since. Machine problem was seen on is using a 72 GB Raptor (10k rpm) drive. I fear this will cause issues with the coming Intrepid release as if the above is true, anyone with a SATA II drive on a SATA I controller is going to have a non-functional install out the box.

Can we get a status update on fixing? I can and will provide any additional details asked for - I think the above has pretty much summed it up though.

This problem also occurs in 2.6.27-4 but with a much lower frequency than in 2.6.27-7.

The HDD connected to the other SATA port works fine. The hardware is Intel based.

@Andy: I am not so sure, my problem is related to bug #290153.

My HDD is not affected by this freeze issue, only my SATA DVD drive.

The DVD drive spins up properly but after spinning down the restart results in a freeze. Since the drive works under Windows I would rule out a hardware problem.

You can try disabling AHCI in your BIOS. Maybe this fixes the problem. Change setting "Advanced"|"IDE Configuration"|"SATA Operation Mode" from "Enhanced" to "Compatible".
However if you have a parallel installation of Windows XP (made in AHCI mode) this will no longer boot.

You may also post to linux-ide to confirm the suspicion of a firmware issue.

If it is really a firmware issue then become an Asus Member ( and file a request like I did. Maybe the more people complain about this issue the higher the chances that Asus reacts.

In 95% when I tried to boot, I got the above mentioned COMRESET failed (errno:-16).
Then, I tried to boot with an old PCI Sata Card with Sil3112-Chipset and.... everything works fine.
After that, I tried the all_generic_ide parameter with the build-in controller (nforce4) and it works too!
So here's my conclusion about this problem:
The sata_nv-driver used by kernel 2.6.27-11 has definetly a problem with some hd-drives like mine.

I thought I should report, this has been started to work for me a
while ago. I'm using proposed updates, and I'm guessing that it's been
working with maybe with kernel 2.6.27-13, but at least with 2.6.27-14
and 2.6.27-17.

After upgrading 8.04 to 8.10 I've experienced this problem too. Adding "rootdelay=240" in grub's boot menu makes the kernel boot, but the error message was still being reported:

ata4: link is slow to respond, please be patient (ready=0)
ata4: COMRESET failed (errno=-16)
ata4: hard resetting link

The kernel in question is 2.6.27-11-server. I had to make 2.6.24-23-server my default kernel for now, until this bug is fixed.

Does anybody have the information whether this bug is fixed in Jaunty ( kernel, at the moment) or not?

I'm attaching outputs of dmesg, lspci -vv, lshw and dmidecode), in case someone needs that data.


I was having this problem with 2.6.27-11-generic, but since upgrading to 2.6.27-14-generic out of intrepid-proposed, it is fixed.

Noticed that this had gone quiet but it's the error I now get. I had this problem with 2.6.28-13-generic on 9.04. My symptom was this: I would get the COMRESET message that everyone else gets, then the filesystem(ext3) would be automatically remounted as read-only. Eventually it wouldn't mount, citing "bad superblock". It worked under a previous kernel(the last RT) but switching back to that kernel didn't help either.

Since I didn't have any more time to throw at this, I did the quick-fix:

edit /boot/grub/menu.lst

find the "kernel" line of the in-use kernel.

add " noapic nosmp" to the end of the line.

Save, restart, pray.

Hope this helps someone. Not sure if smp and apic really boost the speed of a system in the way that anyone would notice, though.

Hi, I can confirm the bug on a fresh installed ubuntu server (9.04).

Linux ubuntu 2.6.28-15-server #49-Ubuntu SMP Tue Aug 18 19:30:06 UTC 2009 i686 GNU/Linux

It's on a Via VT6421 based S-ATA/P-ATA raid controller for PCI.
(Kon Delock Control 70873)

It's not usable (no /dev/sdX for the devices connected to the controller).

I get similar errors on a NVidia 750i Motherboard with Pentium D Extreme Edition..
XFX, from whom I got this motherboard have deprecated the kernel and no longer support
the Pentium D Extreme Edition, I have a copy of the kernel flash image if you want
to have a look, and maybe compare it to the new BIOS flash.

I'm using Ubuntu 9.04 32-bit with the additional set of Ubuntu Studio packages,
was trying to run the realtime kernel (most recent), and with almost all my USB devices
disconnected, only PS/2 Keyboard and a USB Mouse. I tried a number of things,
without a clue what would work:

Running CPU in normal 3.73 Ghz mode with 800Mhz DRAM. I have overclockable ram,
BTW.. 4.256 Ghz, with 800Mhz RAM.. 4.256 with 1000Mhz ram. In every case I got errors.
I tried changing the PCI bus latency 32, then 128, then back to 64.. I tried turning
hyper-threading off. I haven't tried turning AHCI off.

I couldn't find the occurence of DRDY in my log files..

Two drives are connected to the controller, but only one has issue. Problem drive is WD 2TB My book. Not using RAID or SoftRAID. I do not boot from this drive.

Drive mounts ok if it is not plugged in during boot. The drive also goes away after sleep/resume with same error.

MOBO is HP/Asus M2N61-AR. Bios is latest and can see drive no problem. Win 7 also has no issue. Dual booting with Win7 64 bit and Kubuntu 64 bit kernel 2.6.31-15

Most of the times it happens on sata port 2 but i believe it also happend on another port. Like earlier mentioned it can happen five times a day, but sometimes it takes 2 weeks to start this error messages (link is slow to respond, please be patient (ready=0), SRST failed (errno=16), limiting sata link speed to 1.5gbps, reset failed, giving up).

Untortunately i cannot add dmsg/pci info easily.

Is this really a corner case bug or is it just the hardware?

I have had this happen to me with 3 different drives and the drives are brand new and they work fine otherwise.

I have checked the cabling and I have the locked SATAII cables. All the drives are SATAII and nothing in the system is 1.5Gbps. So, this is not a legacy drive phenomenon.

Could it be related to NCQ? When I saw these errors on a drive (which is the oldest of the 3), I disabled NCQ on it (set qdepth to 1) and I haven't seen this on that drive ever since.

Can other people having this issue try turning NCQ off and see if it goes away?
