No. This doesn't look like a hardware problem. It always happens in pretty much the same place. > Three kernel back traces are appended. Do you still have the dumps? The obvious thing to do here is to look at what's going on there. A "page fault" under these circumstances suggests an uninitialized pointer (the fault address is 0x0 in one case and 0x63746572 in the other; the latter is interesting because it is the text "retc"). The first thing you want to do is look at the stack frame where the problem occurred. Do this: (kgdb) f 5 (kgdb) p *ap This will be an iterative effort; it'll take a while to find it, but I'd guess you have a corrupted file on disk.
