[Bug 574462] Re: udisks-probe-ata-smart causes HSM violations

Tue Jul 24 18:08:03 UTC 2012

Jarige, 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 in the
development release from a Terminal
(Applications->Accessories->Terminal). It will automatically gather and
attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

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 . Please do
not test the kernel in the daily folder, but the one all the way at the
bottom. 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. As well, please comment
on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not
boot, please add the tag: 'kernel-unable-to-test-upstream', and comment
as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.

  udisks-probe-ata-smart causes HSM violations

Bug description:
  This is related to bug 445852, it causes the same effects, but under
  different circumstances.

  During boot on an SSD system and when logging in and starting
  something rather IO intense, like firefox, the system freezes for 30
  seconds, and afterwards dmesg shows an error like

    ata2: lost interrupt (Status 0x58)
    ata2: drained 16384 bytes to clear DRQ.
    ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
    ata2.00: BMDMA stat 0x4
    ata2.00: cmd c8/00:40:cb:60:32/00:00:00:00:00/e0 tag 0 dma 32768 in
    res 58/00:40:cb:60:32/00:00:00:00:00/e0 Emask 0x2 (HSM violation)
    ata2.00: status: { DRDY DRQ }
    ata2: soft resetting link
    ata2.00: configured for UDMA/66
    ata2: EH complete

  The main cause of bug 445828 was fixed now, but there are still some
  users who get those HSM violations/30 second hangs during boot.

  Martin Pitt got ssh access to Jarige's machine which is still affected
  (he's willing to provide access to other people for debugging).

  A lot of different commands were tried to reproduce this at runtime,
  like

    # for i in `seq 50`; do skdump --can-smart  /dev/sda; hdparm -B254 /dev/sda; sleep 0.2; done
    # udevadm trigger --action=change --sysname-match=sda # (also in a loop)
    # (/lib/udev/udisks-probe-ata-smart /dev/sda &); /lib/udev/udisks-probe-ata-smart /dev/sda

  and so on, but it seems impossible to reproduce at runtime
  unfortunately. I also tried those commands while a "grep -r . /usr"
  was running in the background to induce I/O and disk reading activity.

  The interesting thing is that the bug goes away if you either disable
  /lib/udev/rules.d/85-hdparm.rules, or udisks-probe-ata-smart in
  /lib/udev/rules.d/80-udisks.rules. So this seems to happen in
  situations where there is something reading a lot of files from the
  disk, and hdparm or libatasmart send their ioctls to the drive.
