Package: src:linux Version: 4.19.67-2+deb10u2 Severity: normal Tags: newcomer
Dear Maintainer, I experience the following issue: When the system is running for some time (usually a few days, but sometimes some hours), the load rises to about 5. The kernel log (dmesg) shows this message (and repeats it several times): [196473.819189] INFO: task kworker/u16:0:19009 blocked for more than 120 seconds.

It remains fully usable, top looks like this: top - 17:52:44 up 2 days, 6:57, 1 user, load average: 5.43, 5.21, 4.32 Tasks: 217 total, 1 running, 216 sleeping, 0 stopped, 0 zombie %Cpu0 : 2.3 us, 1.3 sy, 0.0 ni, 96.4 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu1 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu2 : 4.7 us, 2.5 sy, 0.0 ni, 92.7 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu3 : 1.0 us, 0.3 sy, 0.0 ni, 0.0 id, 98.7 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu4 : 0.0 us, 0.3 sy, 0.0 ni, 0.0 id, 99.7 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu5 : 0.3 us, 0.3 sy, 0.0 ni, 99.3 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu6 : 0.0 us, 0.3 sy, 0.0 ni, 99.7 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu7 : 1.0 us, 0.3 sy, 0.0 ni, 98.7 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st MiB Mem : 31998.7 total, 26462.0 free, 1366.2 used, 4170.5 buff/cache MiB Swap: 32595.0 total, 32595.0 free, 0.0 used. 29682.1 avail Mem At shutdown, the system hangs for about 20 minutes with the message "watchdog: watchdog did not stop" (quoted from mind memory) until it finally shuts down. This is always related to the increased load and the respective dmesg messages. I experienced this behaviour about 20 times within the last few months. I did not find any workaround t solve this situation.
