Public bug reported:
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 jarikvh'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.
