kernel BUG at /home/apw/COD/linux/fs/btrfs/inode.c:3962!
A bug you all might be interested in. If I can provide any more information,
please let me know. The command that crashed was find, being run by updatedb
(daily cron job). I can''t tell from below which partition it was
looking at,
but I have two raid1 (both data and metadata) btrfs filesystems:

Cheers, Bob McElrath
"The individual has always had to struggle to keep from being overwhelmed
by
the tribe. If you try it, you will be lonely often, and sometimes frightened.
But no price is too high to pay for the privilege of owning yourself." --
