Hi!
Is there any type of hot key sequence that can be used to create a system
dump even after the system has frozen?
I'm running 2.2.5 on a Compaq AP200 with an AHA-2940UW (for the boot drive)
and a QLA2100F for connectivity to an external storage device. I have the
Qlogic card as a module and insmod'd it. When I do a dd (like #dd
if=/dev/sdb of=/dev/null bs=16384 count=500) or try to send I/O to the
external storage via an app called Iorate, I get the message below and the
system freezes.
I can't figure out what the fault address is referring to either. I did a
#ksyms -m | sort and there's nothing that refers to the fault address of
00000000.
Any suggestions are greatly appreciated. Thanks!
Heather
