Description Mike McLean 2003-09-23 12:08:50 EDT
* Severn-0.93.2-i386
* raid5 on /usr

Got the following oops.  Console was locked so I could not tell when it
happened, but it was most likely during or very shortly after the boot process.
 The machine is a Proliant DL380 G2 with a smartarray (cciss).  Will try to

from the oops: 2.4.22-1.2061.nptlsmp
i.e. kernel-smp-2.4.22-1.2061.nptl.i686.rpm

Comment 4 David Woodhouse 2003-09-25 09:57:12 EDT
I see similar oopsen, and also silent lockups, lockups with just 'Unable to
handle kernel NULL pointer dereference' and oopsen with kernel threads
apparently trying to access user space. 

kernel-smp-2.4.22-1.2061.nptl.athlon.rpm, again with RAID.
Comment 5 Dave Jones 2003-09-28 21:05:06 EDT
Should be fixed as of 2075, please reopen if it reappears.
