I just rebased bcache-3.10-stable and added the fix you tested to it.

Also, HEAD in the bcache repository now points to bcache-3.10-stable and
not bcache-for-3.10.

Can you run echo t > /proc/sysrq-trigger when things get stuck, and give
me the full dmesg output?

Hi just before closing I did still following.
root@server:/# du -sh root
332K	root
cp -av /root /tmp/bcache/
sync

Until here everything is OK
Now I enter the following
root@server:/# du -sh etc
12M	etc

cp -av /etc /tmp/bcache/
sync
And the sync command will not come back!
The dmesg I send by mail
