Greetings:
During the rmmod of a fairly simple driver, I get a kernel
panic which crashes the system. I believe I have taken all
the proper steps to attempt to debug the problem to no
avail.
Any suggestions as to how to move further, or how to frame
this question in a more appropriate manner for this list (or
perhaps there is a more appropriate list that I should be
sending this to) would greatly be appreciated.
Please cc me on any reply
Kindest Regards
Jerry
