Description Kenny Simpson 2006-01-19 06:40:56 UTC
Distribution:  Debian Sarge
Hardware Environment:
Onboard Adaptec RAID with zero-channel controller
conntected to 4 Seagate drived in RAID 10

Software Environment:
2.6.15 kernel.

Problem Description:
When a scsi command failed, an oops would result.

Steps to reproduce:
Back-to-back SMART queries would make the Seagate drives unhappy.  The second
SMART query would timeout, and the command would be aborted.

Here is a patch which fixed the problem, but I see it not applied as of2.6.15.1:

Thanks for this patch.

It is now included in Linus' tree and will therefore be in 2.6.16-rc3.
