btrfs check bug

[Jan Koester]

Hi,

i have to try to create a new extent-tree after checksum error not solveable 
with srub or init-csum-tree.
Now i got this failure output from btrfs --repair:
 
ERROR: errors found in extent allocation tree or chunk allocation

I have backup of this data i wan't to help the Dev's too fix this bug because i 
have enough hard drives.I can also give remote access to show what happend 
with the filesystem or other thins that could he to fix this bug. I see at the 
moment much things happened on the raid56 code.

mounting failed any file on my filesystem

[Jan Koester]

Hi,

i have problem with filesystem if my system crashed i have made been hard reset 
of the system after my Filesystem was crashed. I have already tried to repair 
without success you can see it on log file. It's seem one corrupted block 
brings complete filesystem to crashing.

Have anybody idea what happened with my filesystem ?
