strange messages "ata3.00: exception Emask (HSM violation)"

[Manuel López-Ibáñez]

Ubuntu is really slow booting and shutting down and I noticed the following strange messages in syslog:

[ 22.028000] ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen

I had a bunch of these, but my disk actually died:

    [440525.460000] ata2.00: configured for UDMA/33
    [440525.460000] ata2: EH complete
    [440942.908000] ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen
    [440942.908000] ata2.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x43 data 12 in
    [440942.908000] res 50/00:01:00:00:00/00:00:00:00:00/a0 Emask 0x2 (HSM violation)
    [440942.908000] ata2: soft resetting port

This is on an up-to-date Feisty system. I noticed because all of a sudden I couldn't write to the disk, and on fsck, it basically dumped everything and I lost everything (luckily, I have good backups). So... is this a problem with Ubuntu corrupting disks, or did my disk die?

[David N. Welton (davidnwelton)]

I looked around on what was left in lost+found, but there's really not much that I could salvage to get information. The disk is one of these:

Device: ATA ST980813AS Version: 3.AD
Serial number: 5NH0301G

[Stefan Handschuh (handschuh)]

This seems to be due to a bad AHCI/ATA-implementation of the countroller in your hdd. You may check out the NCQ-blacklist for more information on your harddrive.
Updating your kernel should solve this problem _some_ time.

[Bernhard Schmidt (berni)]

I hit this issue too,

ata1.00: exception Emask 0x2 SAct 0x4 SErr 0x0 action 0x2 frozen

its a known bug with the ahci driver and fixed in the following commit to 2.6.22-stable

http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.22.y.git;a=commit;h=2370eae7567e06b10f68ce293cb2a6b4f773b0c7

Applying this patch and recompiling the kernel fixed this issue for me

Model Family: Maxtor DiamondMax 10 family (SATA/300)
Firmware Version: VA111900

it doesn't apply cleanly because the Ubuntu developers have changed the blacklist already, but the driver part is okay.

[Launchpad Janitor (janitor)]

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

[Leann Ogasawara (leannogasawara)]

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.

--or--

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 http://www.ubuntu.com/testing 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.

[Bernhard Schmidt (berni)]

As linux-2.6.22 is marked "won't fix" and the AHCI fix is incorporated in the vanilla 2.6.24 it should be fixed for Hardy and Intrepid. I can't say that this way of totally ignoring bug reports makes me want report more bugs in the future.

[Leann Ogasawara (leannogasawara)]

Hi Bernhard,

Thanks for the note. In order for patches to qualify for a Stable Release Update they need to be confirmed as fixed in the current development release - https://wiki.ubuntu.com/StableReleaseUpdates . You mention this should be resolved for you at least with Hardy and Intrepid. If you could just do a quick test with say and Intrepid LiveCD just to confirm that would be great. Then we could open a Gutsy SRU nomination. Thanks.

[Brad Figg (brad-figg)]

This bug report is being closed because we received no response to the previous inquiry for information. Please reopen if this is still an issue in the current Ubuntu release, Jaunty Jackalope 9.04. To reopen the bug, click on the current status, under the Status column, and change the status back to "New". Thanks.

[Boris Malkov (hori24)]

The same behavior in Karmic with all updates. The HDDs are SAS ones on LSI MegaRAID 8300XLP controller.

[Boris Malkov (hori24)]

This part is repeating in the syslog every several minutes:

[425954.573268] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen

The machine freezes at that times.

PS acpi=off in the grup.

Hi manu,

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/ .

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 163637

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.

^ I ran apport-collect -p linux 163637 with current configuration. Since it's the working server, I wasn't able to try a development version, but I'll try it next few days when I'll be free to shut it down.
