I'm far from an expert here, but perhaps you would be worth trying a
newer version of the BTRFS drivers, either via a newer kernel or
re-compiling a kernel with updated BTRFS patches.

I would think that the simplest "quick test" to see if this would help
you would be to get a snapshot from Ubuntu's "daily build" live CD iso,
and try mounting the filesystem with that... since it will have a recent
RC of 2.6.38 kernel which has a much more recent BTRFS version than the
2.6.34 which you are using.

YMMV, but it's certainly something else to try.

Hi,
I am using btrfs on my /home successfully for a while now.
After a power failure I am no longer able to mount it. I tried to use
btrfsck without any success.
The backup I have is about a month old, is there a way I can salvage my files?.
Full backtrace is at http://pastebin.com/4Re7tVFP
 I am aware of the danger of dataloss and wanted to change the filesystem.
Anyway it's too late now
