This bug has happened again. This is only the second time, and I'm
really not sure how to replicate it. However there does appear to be a
deadlock (or a crash with a lock held) happening.
This trace has a couple of threads that are a little past
queue_log_writer:
One has a frame like "[<ffffffffa0384eec>] ? open_xa_root+0x8c/0xf0 [reiserfs]"
after queue_log_writer.
Another has a frame "[<ffffffff81195486>] ? mark_buffer_dirty+0x66/0xa0".
The first program that froze (that I noticed) was emacs (3308).
** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed
** Attachment added: "Another trace of the freeze."
