kernel failure

[golinux <golinux@riseup.net>]

I use squeeze LTS as a desktop, not server.  Upgraded the kernel a few 
days ago.  Everything was working as usual.  Then out of nowhere I get a 
kernel failure popup after coming out of suspend. I sent the error to 
the kernel folks and everything seems to be working OK since then so 
I've just gone on about my business.  But I don't want to get bit by 
this down the road.  What should I do? This has never happened in the 10 
years I've been using Linux so I'm a little lost.  Here's the log:
