Hi,
I've got the same issue. Btrfs FS crashes on my box running Linux 3.11.7.
It seems that the crash happens when I start collectd daemon. Maybe a
corrupted RRD file somewhere.
I don't have time for debugging this issue further so I'm going to
re-format this box to ext4. Btrfs is statically compiled in kernel so
I'm unable to gdb btrfs.ko. No debug info in kernel image. Sorry not
being able to help.
/dev/sda2 on / type btrfs (rw,noatime,nodiratime,ssd,space_cache)
Mount options used to have also autodefrag but I removed it while hoping
it would make the box more stable.
