Dear all (please keep Cc)
Since 3.16-rc3 or so I regularly get btrfs hanging in some transations. Usually during apt-get upgrade or some other large file operations (cowbuilder building of packages). The log files give me for loads of processes things like: [ 6236.746546] INFO: task aptitude:22775 blocked for more than 120 seconds. [ 6236.746547] Tainted: G W O 3.16.0-rc5 #27 [ 6236.746548] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

This time, issueing a Sysrq-s for emergency syncing did the laptop out of the hang. Hardware: Sonly VAIO Pro 13 Distribution: Debian/sid self compiled kernel, config on request. Please let me know if there is anything else I can provide.
