Re: libata badness

I just got another oops while trying to cp from my md/raid5 array (2 of 3 
sata drives) to another sata drive on the same controller. This time, 
though, it said there's a bug in timer.c, line 405, and that the 
stack's garbage. I'm thinking it has nothing to do with timer.c, and 
something in md or libata is chomping all over the kernel.

Or else something else on your system is bad.  Like your CPU or RAM.
Run memtest for a while.
