Sweet! I'm impressed that you found such an obscure bug. Could you go
through some of the steps that you went through to do this debugging? I
would suggest the following mentionables:
1) enabling kdb
2) interpreting the data
3) What made you zero in on that particular memset (ties back to #2)
4) Documentation that says the __pb_block_prepare_write already kmap'ed
the page. If the answer is "use the source Luke" then so be it
Congrats!
Blue skies... Todd
