JFTR: I chased "random" panics for some time on my Acer AK77-400.
Thought bad memory, ran memtest86 and it was confimed... NOT!

Turns out that although the board supports DDR.../333/400
(PCwhatchamacallit/2700/...) and has three slots, there is not enough
bandwidth to run @ 400 with all three slots populated. At 333, all
memory tested good.

*After* I was made aware of this niggling little inconvenience, I had to
make the tough choice between faster or more memory. *sigh*.

I had found a post about it somewhere, but I can't locate it now. I hope
this is not your problem... or maybe it is better than bad memory?
