aacraid and smp kernel: SCSI hang
Greetings all,
Our main server is an Opteron system with an Adaptec SATA RAID 2410SA
controller and 4x 250GB Seagate Barracuda disks attached to it, forming
a RAID-5 and a RAID-0 container. The system is running sarge with the
latest 2.6.8 kernel (2.6.8-13-amd64-k8).
We recently upgraded the server with a second Opteron CPU. When we tried
to boot the system with the SMP kernel it gave the following messages
just after the login prompt and hung:
Nov 9 09:52:58 myhost kernel: aacraid: Host adapter reset request. SCSI
hang ?
Nov 9 09:52:58 myhost kernel: aacraid: Host adapter reset request. SCSI
hang ?
Nov 9 09:53:32 myhost kernel: aacraid: SCSI bus appears hung
Sarge 2.6.8 kernels contain aacraid 1.1.2-lk2. I managed to compile and
install version 1.1.5-2400 (downloaded from Adaptec's site) but without
any luck, the system still hangs.
Please note that aacraid 1.1.5-2400 has been used in the single CPU
system (i.e. before the addition of the second CPU) for quite some time,
without any problems.
Has anyone else faced a similar situation?
A google search revealed this is an old bug, dated back to 2003 but with
no clear solution whatsoever.
Any help would be much appreciated. In the time being I have two
options, either remove the second cpu or remove the raid controller,
both of which suck :-).
