Oops from 2.4.22-grsec

From: John Keimel

Apologies if this is poorly directed, but Documentation/oops-tracing.txt
said email this address ;)

Here's my output from ksymoops. I am not running any modules, so I ran
with -K . I am running with grsec patch.

If the formatting is poor, the text is available at
http://www.keimel.com/oops-923-output.txt .

I assume this is going to the kernel list, of which I am not a member.
Please cc: if you can. Thanks.



Output follows:
