Are you sure the hardware is ok? Maybe you
should run "memtest86" on this system
for a couple of hours, to make sure that
memory is still ok.
Did you install any extra device drivers or
kernel modules (things like opensound audio,
community nic drivers, fuse, virtualbox, ...) ?
Maybe such a driver could be the root cause
for the panics?
Running a debug instead of a release kernel
would be another thing that you could try. Maybe
the debug kernel is hitting some failed assertion
and detects some corrupted data structures,
before the machine tries to access the corrupted
data.
With the release kernel, you could try to run the
system with kernel heap memory checking enabled;
maybe that will detect some sort of heap memory
corruption?
