thanks for the report. What kernel version did this come from? Was
it 3.9-rc4? (line 1591 for 3.9-rc3 doesn't contain a BUG_ON).
If it is indeed 3.9-rc4, it would be helpful, since you can reproduce
the problem, to insert a debugging printk which fires when
bh->b_blocknr != pblock before the BUG_ON, and have it print the
b_blocknr and pblock values.
Thanks,
