lsi_scsi assertion

lsi_scsi assertion

[Peter Lieven]

Hi,

I found the following assertion in my log files after a system reset was 
executed

kvm: lsi_scsi: error: ORDERED queue not implemented
last message repeated 5 times
kvm: lsi_scsi: error: Unimplemented message 0x0d
kvm: lsi_scsi: error: Unimplemented message 0x0c
kvm: lsi_scsi: error: Unimplemented message 0x0d
kvm: qemu-kvm-0.12.4.1: /usr/src/qemu-kvm-0.12.4/hw/lsi53c895a.c:596: 
lsi_reselect: Assertion `s->current == ((void *)0)' failed.
kvm: Aborted
kvm errno=134

The guest is a 64-bit ubuntu 10.04 server. Qemu-KVM is 0.12.4.

Sounds this familiar to anyone?

BR,
Peter

For messages 0x0c and 0x0d I recently submitted a patch:
http://thread.gmane.org/gmane.comp.emulators.qemu/79660

ORDERED queue is still missing.
The assertion needs to be investigated. What guest OS?

Already checked if even the abort persists with 0.13-rc1? Just to
exclude that this is only a missing back-port.

hi, not yet. i have not tried 0.13-rc1 because i did not find a valid changelog in the distro.

You mean you did not find any potentially related commit in git? There
were definitely changes regarding reset, and I don't think we have them
in 0.12 yet (backport was non-trivial, /me would have to check our local
patches for 0.12 if those turns out to be the key for your abort).

sorry, my sentence was not clear.

i downloaded 0.13-rc1 tarball from sourceforge and there are no entries regarding
0.13-rc1 in the changelog.

That's the problem with meta-changelogs: someone has to update them
manually. The history is always in git (accessible via web as well).

[Carlo Maraschin]

Hi All,

Just checking what is the status of this bug.

I just tried ubuntu 10.10 with kvm 0.12.5 and I get the same problem, here the
entry from my logs:

kvm: /build/buildd/qemu-kvm-0.12.5+noroms/hw/lsi53c895a.c:596: lsi_reselect:
Assertion `s->current == ((void *)0)' failed.

BTW, It does crash the VM when it happens... (not a very nice bug)

Thanks,

Carlo

Maybe the assertion is a consequence of the improper handling of
messages 0x0c and 0x0d which are SCSI ABORT messages.
