If I am not blind, the task currently owning the cpu isn't listed there, which I suppose to be already running. Next time you hit it, could you please paste the stack trace of the task owning the cpu? Which I suppose to be xfsaild according to your report. A simple `cat /proc/<pid>/stack` is probably enough thanks > > * dmesg output from hung tasks > [25012.200938] INFO: task kworker/u12:0:39771 blocked for more than 120 > seconds. > [25012.201036] Tainted: G E 4.11.0-rc5-mw #1 > [25012.201125] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" > disables this message. > [25012.201220] kworker/u12:0 D 0 39771 2 0x00000000 > [25012.201229] Workqueue: writeback wb_workfn (flush-9:127) > [25012.201231] Call Trace: > [25012.201241] ?
