Side note, I could not have a look at your config/dmesg etc.
tarc.po.cs.msu.su could not be found.

Yeah, buildkernel and buildworld are good stress tests. The same as a
gcc bootstrap is.

Here my side note 2, it's not on x86, but on ppc. I have a powerbook
with one GB of ram. Doing buildworld and buildkernel ended up in such
sig 11 failures at random places. Not reproducable.
I know my hw is ok, I do daily gcc bootstraps and the machine works. But
under fbsd ppc I got the above sig 11 issues. A short talk with Peter
Grehan made me try to reduce the physical memory software side with
hw.physmem=512M. Bingo, that was it. I could do buildkernel and
buildworld with hw.physmem=512M. No problem. So, our thinking is, that
there is a trouble with physical mem > 512/640MB on fbsd ppc.
This note may not help in your case since it is on ppc fbsd. But maybe
it gives you another idea?

Andreas
