Can you look also the first trace?
Here a same error message "sleeping function called from invalid

Yes, the monitor still turns off after applying patch "make the pool
shrinker lock a mutex".
Anyway patch fixed the issue with flood of message "BUG: sleeping
function called from invalid context at mm/vmalloc.c:1756" so kernel
log became cleaner.
Now the issue with turns off monitor looks in logs so:

You said that I need open up a bug report you means site
https://bugzilla.kernel.org ?
I thought mailing lists is better because bug report on
bugzilla.kernel.org usually leave opened for several years without
attention.
