Description Mike McLean 2003-09-23 17:30:57 EDT

* Severn-0.93.2
* seems to be only smp machines
* kernel-smp-2.4.22-1.2061.nptl

I'm seeing several smp machines die at various places with only the message
"Unable to handle kernel NULL pointer dereference"

Comment 1 Mike McLean 2003-09-23 17:44:34 EDT

I got the following peculiar serial log from one machine as it died.  It appears
to contain several overlapping kernel error messages including a NULL
dereference and a kernel BUG.

Comment 2 Mike McLean 2003-09-23 23:59:14 EDT

whee, it's like a word find.

I've managed to disentangle the following strings from the mess above.

Unable to handle kernel NULL pointer dereference at virtual address 00000282
 printing eip:

*pde = 00000000



Some of it appears to be corrupted.  Looks like there might have been a page
fault too.
