From time to time I am getting SCSI errors from the guest using the
latest CVS:

scsi : aborting command due to timeout : pid 50803, scsi0, channel 0, id 0, lun 0 0x2a 00 00 3d be 84 00 00 08 00 esp0: Aborting command

SCSI bus is being reset for host 0 channel 0.
esp0: Resetting scsi bus

As far as I can tell the guest recovers fine, but it may be worth investigating.

I reported similar errors recently (OS X ppc host) - for me it panics afterwards and does not recover fine. I got the impression that it happens later if I disable the lance NIC.
