Last night I have pulled and installed latest kernel and immediateley
noticed that git pull on btrfs file system is stuck.
Io wait was high without noticing that there is something
to wait for. Also noticed that btrfs_transactio process was
stuck with 'D'. Tryed sync and that also got stuck.
I think that this is easilly reproducable and noticable.

Branimir.
