Unforutnately there really isn't any kind of backtrace info given by the
All that it says is (hand copied)
scsi0:A:1 ahc_intr - referenced scb not vlaid during seqint 0x71 scb(0)
scsio: Dumping Card State in Message - in phase at SEQADDR 0x1c1
Kernel panic: for safety
In interrupt handler - not syncing
<0>Rebooting in 180 seconds.
I found the line in the aic7xxx.c file which prints this. It seems
ahc_lookup_scb() returns 0 and then it does the kernel panic.
I can't seem to find any backtrace info for the System map. and none of
the messages get written to log - I guess because no sync is done?
I would be happy to copy down all of the Adaptec debug info but I am not
sure it will help.
Is there a way to force ithe kernel to drop into some sort of debug mode
upon doing a "panic"?
