Thank you for this information. I have this commit on my branch as it is
based on staging but I didn't know that it could be a fix for the
problem. Therefore I haven't tested this until now.

After first test I was going to write that currently even after
"decalibrating" timer frequency (reverting my "fix") problem doesn't
appear but tried again, and unfortunately it failed. After 8 attempts I
had 2 failures and 6 successes.

Definitely something on staging helped. Probably this commit. But the
issue still exists and I leave it on my todo list for later.
