Subjectkernel NULL pointer help...
Hello...
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 (an EMC
Symmetrix 3930). I have the Qlogic card installed 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.
Any suggestions are greatly appreciated. Thanks!
Heather
