If these messages are not handled correctly the guest driver may

Always mandatory:
- ABORT
- BUS DEVICE RESET
Mandatory if tagged queuing is implemented (which disks usually do):
- ABORT TAG
- CLEAR QUEUE

Nicholas, as you seem to have touched the lsi code recently, care to
review this one? Assuming that you are reasonably familiar with
both the
hardware and the code, you should be quicker than me with this.
Is there a reason why this patch was never added to the stable
qemu-kvm release?
At least int qemu-kvm-0.14.0 I still can't find it.
The reason is that it still didn't get a review.
I still depend on this patch. It's needed for our legacy guest OS.
It's heavily in use here with STGT iSCSI disks via scsi-generic.
i recently saw some qemu-kvm 0.12.5 guests with scsi and this patch
applies crashing when
we updated our backend iscsi storages. (short interrupt in traffic flow,
iscsi disconnect + reconnect)
i always see:
lsi_scsi: error: ORDERED queue not implemented
and then either the maschine just hangs or it even aborts due to this
assertion:
qemu-kvm-0.12.5: /usr/src/qemu-kvm-0.12.5/hw/lsi53c895a.c:596:
lsi_reselect: Assertion `s->current == ((void *)0)' failed.
any ideas?
