So long as I don't have to claim it :)

What I know is an IDE bug introduced between 2.6.8.1 and 2.6.8.1-mm4.
So far all I have done is spent a couple of minutes tracking
down my the kernel was oops on bootup.

The new code introduced between those two kernels seems
to be the enhancement to ide_dump_status introduced in
ide-disk-barrier.patch The amd74x driver has remained
the same. So if ide_dump_status is correct it appears
it has uncovered and old bug.

Here is the oops that I get without this patch. The drive
in question is a compact flash device. So it implements
only a minimal number of ide commands. Which explains the
presence of errors.

There is a truly trivial amount of driver specific code
on this path. So if the problem is not the code I patched
it appears to be a generic IDE bug.

Also attached are my complete boot logs in the patched and
unpatched case.
