Hi Chris,
Both BUGs seem to be related to some kind of race (the first one is a
check for mm->map_count !=0 on exit_mmap and the second is a BH_Lock check
at submit_bh()).
First try to not use the md0 (use md1 or md2 directly then reconstruct the
mirror later).
If that fails, recompile your kernel without SMP.
It might me a JFS problem.
