what are the test you are using. I have a couple machines here I could
probably have the tests running on.

Hi All,,
I'm trying to debug this panic that I emailed the list about the other
day... I've gotten a little way with KDB - just wondering if there's
someone familiar with the internals of dm-raid1 that I can bounce
things off as I find them (lest something I find jog inspiration with
someone who actually knows what's going on!).
The crash occurs here in rh_dec(), called by mirror_end_io():
if (atomic_dec_and_test(®->pending)) {
Because reg is a null pointer, returned by __rh_lookup()
That's as far as I have gotten so far :)
The crash is not complicated to reproduce but it does take quite a
while doing heavy i/o before it crops up. So it might be an hour or
so before I can get back into my KDB session with the same problem
(there is a deadlock problem as well triggered by the same steps).
Anyway - if someone is willing to lend a hand please let me know!!!
Cheers,
Tim
