Re: 2.6.3-mm1 and aic7xxx

["P. Christeas" <p_christ@hol.gr>]

Just noted some nasty behavior at 2.6.3 ( not -mm1) wrt. aic7xxx.

With 2.6.2 I hadn't noticed any trouble (for the last 6 days I've been running 
it). Now, the box hung twice, while trying to use the scsi cd-recorder (HP 
m820e) I have. The machine is 'blind' (i.e. no console) so I couldn't get any 
trace/logs..
First time was while starting 'cdrecord-2.0'. Just when trying to query the 
device. At the same time the scsi bus was accessing an iomega zip100 drive, 
reading data.
Second time must have been the device scanning done by k3b (I believe it uses 
the same scsi libs as cdrecord). Note also that I have an atapi (not 
ide-scsi) recorder, which had been fixating the disk it had written when the 
box hung.

Does this relate to the problem you mention ? 

 I could only recover the following log: (0 4 0 is the scsi M820e recorder)

SCSI error : <0 0 4 0> return code = 0x70002
