Server death (RELENG_5_4)

[Schi Zoo]

Hello everyone...
I hope some will give me a few clues where to look...
5.4-STABLE-p7 panics here....

Nice panic screens:

Dmesg: http://www.divo.ru/~lesha/dmesg.txt
(note ram is limited with hw.physmem=1900M)


after pfault2:

At the time of panic gcc was doing "make buildworld" and also bailed out
just before panic:

cc -O -pipe -march=pentium4 -I. -I/usr/src/lib/libncurses

also I was running "fstime" from "unixbench" package:

I hope someone will give me some guidance where I should look....
