Comment (by [EMAIL PROTECTED]):
I got the LKCD kernel patch and utiltities working on my machine. I've
got a crash dump. I'm looking at a stack trace in lcrash. I don't really
know what to do with it. Now what? :)
When I updated to the r1453 drivers the stack trace from the oops message
changed. I've seen this new stack trace several times now, and I have not
seen the trace with xfrm_policy_gc_kill a second time.
New oops message:
