btrfs receive hangs in "uninterruptible sleep"

["Marko Schütz Schmuck" <MarkoSchuetz@web.de>]

Dear All,

for backup purposes on a laptop I use a shell script that takes
snapshots and then btrfs sends the increment to a btrfs receive to an
external USB drive. This used to work for years. The last time I used
it successfully was mid-January. After that I have not been able to do
a successful backup. It seems the btrfs receive hangs in
"uninterruptible sleep". I turned on verbose output and can seen that
it hangs predictably at the same file after `df -m` on the target file
system reports 44MB more space used and 30MB less space available. At
that time the `btrfs receive` has used 6s of CPU time. I cannot kill
the `btrfs receive` and a shutdown does not go through (I have to
power off).

I have tried booting into an older kernel version, btrfs scrub, btrfs
check. Always the same.

Needless to say this is annoying: my main reason for using btrfs was
the backup using send/receive ...

Any help is greatly appreciated!

Best regards,

Marko
