hail,

since that day, this box is running Folding at Home in its single core
client (the one that freebsd has also) and is ok. I have a two core vm,
running amd64 Debian and jut one cpu is full load.

I tried to reproduce this at home, but no luck though. Same Core 2 Duo
E6750, but this time 8-BETA2 and Zotac nVidia based motherboard. This will
only work in 7.2 amd64 ?

by moving things around, dd if=/dev/zero of=any_file suffice ? I got it
writing about 380MB. My virtual disk is small, so I can go as high as
600MB.

so here, just the folding smp client makes my pc crash.
single_core+vm+vt+amd64 is fine.

thanks,

matheus
