Got another "invalid opcode" in btrfs-fixup-0. That was in the
middle of transfering a 3.6GB file. I've got one and only one of
those during one boot time when doing that rsync.
When the btrfs_inode_cache grew dramatically before the crash,
It was in the middle of transferring an area that had hundreds
of thousands of little files
Any idea anyone?
Best regards,
Stephane
