After about two minutes the following message is displayed: Oct 17 18:47:06 Kahlan kernel: [ 363.170588] INFO: task kworker/u8:2:186 blocked for more than 120 seconds. Oct 17 18:47:06 Kahlan kernel: [ 363.170592] Tainted: P OE 4.13.0-12-generic #13-Ubuntu Oct 17 18:47:06 Kahlan kernel: [ 363.170593] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. Two Minutes later this message is displayed: Oct 17 18:49:07 Kahlan kernel: [ 484.008650] INFO: task kworker/u8:2:186 blocked for more than 120 seconds. Oct 17 18:49:07 Kahlan kernel: [ 484.008659] Tainted: P OE 4.13.0-12-generic #13-Ubuntu Oct 17 18:49:07 Kahlan kernel: [ 484.008662] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. This message repeates itself. If I am lucky, my laptop shuts down after some time. Also standby does not work. I think my wifi-adapter causes this problem. With Ubuntu 17.04 or Suse 42.3 I cannot reproduce this problem. I found a bug report in the Arch Bug System (https://bugs.archlinux.org/task/55872 In my laptop I have also a Qualcomm Atheros Adapter. Perhaps the linuxkernel has a bug?
