Hi.
    I recently upgraded my PC to one of there new Celerons with EM64T 
(is it supported at all?). It runs NetBSD/i386 very well. I didn't 
experience single lock-up or panic since I upgraded. Unfortunately, 
NetBSD/amd64 doesn't work very well on it. Under heavy load system often 
crashes. For example like this:

fatal protection fault in supervisor mode
trap type 4 code 0 rip ffffffff8039e282 cs 8 rflags 10286 cr2 
ffff80002478d000 cpl 0 rsp ffff8000256a4c30
panic: trap
syncing disks...

I tried 3.0 and -current (GENERIC and my own kernels) and it always 
panics after few minutes of compiling.

dmesg: http://strim.aster.net.pl/workstation-ii-amd64.dmesg
config: http://strim.aster.net.pl/WORKSTATION-II

I can rebuild the kernel with DDB enabled. I'm no kernel hacker, but if 
someone would be kind enough to explain me what should I look for, then 
I could help fixing this.

I'd really like to use NetBSD/amd64. Any ideas?
