Btrfs devel - Feb 2011 - Kernel 2.6.35 (Ubuntu 10.10): Unable to mount (orphan list)

Hi,

I''m using btrfs on Ubuntu 10.10 for some test partitions.
After doing some normal operations I suddenly couldn''t mount the
partition anymore.
I always get the error "BTRFS: inode 120790 still on the orphan list"
in the kernel log again and again and it''s impossible to stop the mount
command or shutdown the system.
Any ideas how to work around this issue?

Thanks!

Best Regards,
Tobias

Josef was looking at this recently but the fixes had problems for .38
and we had to push them off.

Which kernel is ubuntu on?

I tried the official maverick kernel (2.6.35.25.32) and the ppa kernel
2.6.38-rc6.

Are you speaking of this patch? https://patchwork.kernel.org/patch/530421/

I''d like to help troubleshooting this issue. Any hint how I can help?
Can I manually correct this orphan list? It would be very nice if I can mount
this partition again and not lose it''s data.
BTW: It''s always the same inode number...
