Subject: Re: kernel BUG at fs/btrfs/extent-tree.c:1353
It's getting worse. The /home partition is now affected too. I get the Oops on
simple unmounting the fs. btrfsck gives me this output on this fs:

Mounting the fs read-only an reading the content works fine so far.
I've three systems running with btrfs, a dual Opteron (252), a Pentium 4
system and a netbook with N270 Atom. The netbook is the only one that shows
the errors. It's also the only system where I'm using gcc-4.5. Perhaps it's
related, but I doubt it's the only reason as I'm using gcc-4.5 since May.
regards,
Johannes
