Description Alex Oleshkevich 2024-03-11 18:36:41 UTC 
SUMMARY
System randomly hangs and only hard reset (long press on power button) helps. I observe no pattern, nothing. It just happens serveral times per hour regularly. 

Symptoms:
1. first bluetooth mouse become irresponsible
2. in couple of seconds hangs everything.

In logs I see some references to baloo so reporting issue here.

See attached log from `journalctl`.
