I uploaded your dmesg output to
http://userweb.kernel.org/~akpm/stuff/messages.txt

I'm looking at those traces and am not able to develop a theory to
explain it :(

There's some libata implication at timestamp 13203.385345 but that
looks like it's just a fluke.


So I'm stumped, sorry.  Maybe someone else can think of a way to attack
this.


btw, why does your kernel say "To Be Filled By O.E.M." in the traces? 
The kernel.org kernel doesn't do that.  Is that kernel patched at all?

Thanks.
