Hello!
I started to get these error messages about once a month, but when I get this the whole system freezes and the only way is the hard reset.
INFO: task systemd-logind:741 blocked for more than 120 seconds
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message
INFO: task mysqld:1847 blocked for more than 120 seconds

INFO: task auditd: 716 blocked for more than 120 seconds
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message
...
What can cause this?
