The 815 chipsets have known (and documented) problems with out of spec
memory signals. Board vendors are supposed to have used workarounds but I
have so far sent back 2 out of the 3 A/Open i815 boards with problems where
they locked up occasionally under high load (in any OS) and also failed
memtest86 (with known good tested ram) when placed in an electrically noisy
environment.

I've seen lockups on high network load as part of that - but not packet size
dependant ones.
