Hello!
We seem to have done something to our backup volumes while switching
between 2.6.33.2 and 2.6.35.4 which is now causing this crash while
booting either kernel and mounting one of the volumes. Crash from
3.6.35.4 plus Li Zefan's free-space-cache.c patches. extent-tree.c
is untouched, but if needed, we can try again with clean 2.6.35.4.

Will try 2.6.33 again tomorrow. btrfsck runs for about 44 seconds and

How large is the FS ? Is it possible to run btrfs-image and send the
output file to us?

It's 3 TB. I was running btrfs-image since last night but my ssh got
disconnected before it finished. I'm running it again in screen now, but
the image it made before was 3.8 GB. Would this be useful to you?
We have a number of file systems of this size, and they normally look
something like this (note compress-force is being used also):
Data: total=2.87TB, used=2.09TB
Metadata: total=44.13GB, used=27.04GB
System: total=12.00MB, used=368.00KB
