I'm running 6.2 on a testbed now, see if it stays up. So far 12 days, so
 not much to say yet.
Could it be an idea to comment out pseudofs and procfs from the 5.4
machine? As I understand the handbook, it's not technically needed. I
can't find much more on the actuall problem in procfs, I wonder why not
more people have had this problem.

I found a thread on freebsd-hackers, someone with the same hardware and
the same version (well, 5.5 instead of 5.4) who has the same random
crashes. He upgraded to 6.1. I'll contact him to check what he found out.

Thanks for the tip!
