Hi,

Mount options are:
rw,nosuid,relatime,compress=lzo,ssd,discard,space_cache,inode_cache
The FS is on LVM on a Vertex II SSD disk.
If I run a scrub it aborts after reading 1.8GB and some more lines appear in
the kernel log:
[ 1066.807925] btrfs bad tree block start 0 40044888064

[ 1066.808822] btrfs bad tree block start 0 40044888064
Are there any patches I can try to see if they fix this?
I''m available to run some tests or provide more info if required.
Thanks.
