[guest] And finally the device gets offline
[guest] sd 0:0:0:0: rejecting I/O to offline device
Is it possible, that those problems come from the fact, that I have configured raw devices as kvm disks? Eg:
-drive media=disk,if=scsi,boot=on,file=/dev/sdb2 -drive media=disk,if=scsi,boot=off,file=/dev/sdc2 ...

Update_1:
while guest was panicking, I was able to see SEGV for it's host's qemu process. No core file though. I'll try next time
happened on kvm72 as well.

I know this bug happens even in non-virtual machines(browsing internet shows that clearly), but inside kvm I'm getting excessive rate of this bug (under load, even few times a hour)
An example can be found at end of this message. The record was something...

I can confirm, that kvm-70 still have this issue(or similar). I tried 8139cp & e1000 network drivers, both segfaults with following bt.
host is Fedora8 64bit 2.6.25.6-27.fc8 with kvm modules loaded from kvm-70
guest is running RHEL51 64bit (2.6.18-92.1.6.el5) 6Cpus, 5G RAM
Note, that I had no such issue, when guest was RHEL4u6 64bit. Just upgraded and encountered this problem.
