Bug description:
My btrfs filesystem will not mount almost every boot for a few weeks
now. The only way I can currently fix this is to network boot into
rescue mode to clear the log, would be great to import this into
vivid.
It appears to be this issue:

> Stable kernel version 3.19.1+ can cause a deadlock at mount time
> workaround: boot with older kernel, or run btrfs-zero-log to clear the log
(beware of the consequences)
> fix: scheduled for 3.19.5, or apply 9c4f61f01d269815bb7c37.
> also affected: 3.14.35+, 3.18.9+
