I've been using a recent version of -3.4-stable with no problems.

Given the nature of the trap (page fault in kernel mode) *and* the
reported associated problems of large files getting corrupted in
transit, I would strongly suspect problems with RAM.

1) If you are overclocking either the processor or RAM (not that you've
said you were!) step it back down to its listed speed and see if that
corrects the problem.

2) Remove each bank of RAM one by one (or swap it with other equivalent
RAM) and see if that corrects the problem.
