Hi All,
after a crash for reason not related to btrfs [*], I was not able to
mount the root filesystem anymore. To investigate a bit I started from
another filesystem and I tried to mount manually the FS.
I run "mount /dev/sdd3 /mnt", but the command never returned.
The system was responsive: I was able to start a kernel compilation, to
launch a new shell... But the mount process stuck in 'D' state.
After 120sec in the log appeared:
Apr 30 18:47:14 venice kernel: INFO: task mount:2043 blocked for more than 120 seconds.

"btrfs check" (btrfs-progs v4.0) didn't report anything.
Doing a btrfs-zero-log /dev/sdd3, solved this problem and now the
filesystem works properly.
Before the btrfs-zero-log I made a btrfs-image (~44MB). If someone want to investigate
this issue more I can provide him the image.
The problem appeared both in the kernel 3.19.1 and 3.19.3.
Let me know.
