Subject: [BUG] Kernel Panic from AHD when power cycling external Disk/Array

Running a 29320R with CentOS 4.3 and 2.6.17.8 installed.


Got this interesting BUG from 2.6.17.8 today. Each time I reset my
external SCSI Disk connected to my 29320R the kernel throws this error
and locks up:

FWIW, this error does not occur with the CentOS stock kernel
2.6.9-34.0.2.EL

And finally, to double reply to my own post, it looks like the changes
made in 2.6.16 cause this issue to appear. 2.6.15 doesn't have any
issue with the array rebooting itself and issuing a reset.
