Btrfs devel - May 2011 - WARNING: at fs/btrfs/extent-tree.c:5695 btrfs_alloc_free_block+0x22c/0x370 [btrfs]()

Yesterday, I compiled the new kernel 3.0rc1 from git, but I never
successed to go over the point: "Removing old temporary files".
Pressing control-c let me boot on, but the pc was the complete time on
very high load. It took me minutes, just to reach the tty login - and
again minutes after login in, that I had my shell and a prompt to enter
something. The load was at that time beyond 10.

Now in my /var/log/messages, I found the following warning - and because
it happens when "removing" temporary/old files, that might be why the
computer has so much trouble:

Do you have the very first full oops?  This has the call trace, but not
the beginning text that describes why we''ve crashed.

Hi Chris,

the log starts here - before May 30 21:40:52 there is for 6 hours
nothing. It''s the beginning of the logging. I''m sorry to say
so, but I''m
absolutely unable to boot into 3.0rc1
I used a complete with luks encrypted btrfs partition, there is only
another /boot partition with ext4 - and this system is running since
march 2010. On other kernels (2.6.38 or 2.6.39) - the logging starts
much more early - but like I said - the load was unbelieveable high the
whole time, the hard disks reached maximum temperature (so it was very
hard to lay the hands on the computer) - and my only explanation are
these entries.
