kernel: 3.7.3 from kernel.org
2 harddisks with btrfs and Raid1, lzo compression
trying to start a virtual machine (qemu-kvm) the system crashed giving
following messages:

right now I copy the data with "restore" from
git://github.com/josefbacik/btrfs-progs (master)
but sometimes I get "failed to inflate: -6" and the system is idle for
several minutes.
What are your suggestions regarding the next steps in mounting the
filesystem, especially do you
suggest to keep the raid devices together or to take off one and try to
mount in degraded mode ?
Is there anything you are interested in to analyse, do you want me to
try patches?
thanks and best regards
Falk Frederich
