I assume these are lvm volumes? Could you sent configuration of these volumes. Also one more kdb command. Back trace all. We need to find out why the pagebuf pagebuf_delwri_flush is currently working

Hmm good point. I assume the option has no affect at this point, but it still would be worth turning it off and see what happens.

OK, you made it a lot further through unmount than before, there are two disk I/O's left until you are unmounted from here, and you are waiting for one of them to complete - not sure why it is not co

Hmm I think see part of the problem; this pagebuf is still ASYNC and DELWRI previously pagebuf_delwri_flush was blindly unsetting both of these even if it skipped doing the io. pagebuf_iorequest will
