Hello. I received several Ooops!es today after upgrading to 2.4.16 + 
preemptive patch from http://www.tech9.net/rml/linux/.

I used this same kernel yesterday without problems, but today it crashed 
miserably after only fifteen minutes.

The first oops! occured after pressing "play" in xmms after having it 
set on "pause" for about ten minutes. Xmms segfaulted (see attached 
oops!), and afterwards X bombed completely. I could log in on two 
virtual consoles, but nothing worked (like "ps ax" etc.), and afterwards 
the machine was completely dead. (I could switch consoles but nothing more).

It seems only the first oops! got logged into /var/log/messages, but 
several others occured while trying to log in on the console.

I think the error message that appeared along with the oops was
"Unable to handle kernel paging request".

I'm running yesterday's version of Debian Sid.

Please email me back if you need additional information!

With regards,
Frode
