If you boot single user is it semi-responsive enough to sysrq+w [1]
and post the resulting dmesg?
>My 3.18.6 works just fine.
What do you get for 'btrfs check <dev>' You either need to run this
from the initramfs (totally unmounted file system) or rescue media
with a decently recent btrfs progs.

I had a similar behavior today after I accidentally pulled the power
plug of my machine (Arch Linux, Kernel 3.19.2). I tried to boot several
times, but "mount" timed out. I booted into a recovery Arch Linux with a
3.18 kernel and my root filesystem mounted without any problems.
Unmounted, ran btrfs check, no errors. After reboot, the filesystem
mounted normally with 3.19.2 again! I tried to reproduce this behavior
on another machine, but so far to no avail.
I'm afraid I wasn't able to gather more debug info. Some more general
info: I'm using btrfs on top of dm-crypt (LUKS), my root is on a SSD,
and I'm using rw,noatime,ssd,discard,space_cache as mount options.

This message by itself is not a "time out" of any kind, it's just a warning
which says exactly what it says and nothing more. If you are certain that
there was no access whatsoever to the HDD/SSD (the access light not flashing),
then yeah maybe it got stuck. But it also could be it simply needed 1-2 more
minutes to complete whatever it was doing.

Do you still have the problem ? Can you pls confirm on the latest btrfs
? Since I am fixing the devices part of the btrfs, I am bit nervous.
Thanks, Anand

I'm having a similar problem. I'm getting some kind of btrfs
corruption that causes a panic/reboot, and then the initramfs won't
mount root for 3.18.9, but it will mount it for 3.18.8.
Running on 3.18.8 eventually caused the panic to repeat, so I'm not
sure that 3.18.9 is necessarily breaking things - it might just be
fussier about not mounting a dirty fs.
I did run a btrfs check --repair and it ended up moving some chromium
preferences from the user profile folder to lost+found. That got the
system to run for about 8 hours, but it still paniced the next
morning. I'm now running on 3.18.7 to see what happens.
Unfortunately I haven't been doing a good job about capturing logs.
I'll try to capture more the next time this happens. I've been
running fine on 3.18 for a while now, so I'm not sure where all of
this is coming from.

This continues to happen. The filesystem won't mount with 3.18.9, but
will mount with 3.18.8.
Here is the dmesg output from dracut on 3.18.9:

Do you have this fix ..
[PATCH] Btrfs: release path before starting transaction in

I don't mind trying this patch if the maintainers recommend it. I'm
still getting panics every few days and 3.18.10 won't mount my root
filesystem, so I've been running on 3.18.8.

Same issue here. Rebooted after updating to 3.19.2 and now I get the
"mount blocked" message and can't boot.

Well there are only two backports in 3.14.35. Most of the ones found
in 3.19.2 are in 3.14.36.
commit f9e2ba638c32dff17ee6404e2c8245fd49d99b8b
Author: David Sterba <dsterba@suse.cz>
Date: Fri Jan 2 18:45:16 2015 +0100
btrfs: fix leak of path in btrfs_find_item
commit 381cf6587f8a8a8e981bc0c1aaaa8859b51dc756 upstream.
If btrfs_find_item is called with NULL path it allocates one locally but
does not free it. Affected paths are inserting an orphan item for a file
and for a subvol root.
Move the path allocation to the callers.
Fixes: 3f870c289900 ("btrfs: expand btrfs_find_item() to include
find_orphan_item functionality")

btrfs: set proper message level for skinny metadata
commit 5efa0490cc94aee06cd8d282683e22a8ce0a0026 upstream.
This has been confusing people for too long, the message is really just
informative.
