From Bugzilla Helper:
User-Agent: Mozilla/4.79 [es] (X11; U; Linux 2.4.18-27.7.x i686)
Description of problem:
I have a dell poweredge 2650 with 2 xeon and a raid 5 installed. From I upgrade
to kernel-smp-2.4.18-27.7.x.i686.rpm the system crash. Console shows I/O errors
and I cannot open anything. In /var/log/messages when system crashs shows:
Mar 21 07:16:52 pc1 kernel: aacraid: Host adapter reset request. SCSI hang ?
Mar 21 07:17:02 pc1 kernel: scsi: device set offline - command error recover
failed: host 0 channel 0 id 0 lun 0
I'd see in a poweredge linux list that people has the same problem with red hat
7.2 in various machines with scsi raid.
I'd installed kernel kernel-smp-2.4.18-26.7.x.i686.rpm and system runs well.
Version-Release number of selected component (if applicable):
what kernel were you running before ?
Today, with kernel kernel-smp-2.4.18-26.7.x.i686.rpm, the system crash with the
same errors (Host adapter reset request. SCSI hang ?).
Does this still occur if you try to use one of our newer errata? for example
kernel-smp-2.4.20-20.7 available from
I have now 2.4.20-20.7smp kernel and works fine.
