Is it just me/my machine or has 3.2-STABLE become rather unstable and
panic stricken (sp)?
Whether it has any correlation I don't know, but it seems to have started
when I got in the the RC5DES project a couple of days ago.
Yesterday I got a panic like:
(no debugging symbols found)...

I decided to cvsup the latest -STABLE sources and with a kernel based on
yesterdays -STABLE I just got (again during a RC5DES run, approx
15 minutes after starting it):

Comments invited, I'll build and boot a kernel with debugging symbols in the
meantime.
