hard lockups with 2.5.75

hard lockups with 2.5.75

[Udo Hoerhold]

I switched from 2.5.73 to 2.5.75 yesterday, and I've encountered three hard 
lockups in the 24 hours I've been running the new kernel.  When I reset the 
machine, I don't see anything unusual in the logs.

The machine is a dual PIII with aic7899 SCSI and 3c905c network on the 
motherboard.  In all three cases where I locked up, there was network and 
disk IO going on.  I don't really have any more info.

If anyone would like to give me a list of things to try, I'd be happy to do 
some testing.

Do you already have all the kernel hacking options turned on? 
Particularly the CONFIG_DEBUG_* options? If not, rebuilding and getting 
the same lockup may provide some additional info. You may also want to 
try with the PREEMPT option turned on (if not aleady).
