Description Clément Vuchener 2023-07-07 14:00:33 UTC 
After an update, my tvheadend service is not responding. It cannot be restarted and prevents a regular shutdown. Trying the previous kernel fixes the issue.

Reproducible: Always

Steps to Reproduce:
1.Boot linux 6.3.8-200.fc38.x86_64

Actual Results:  
The tvheadend service does not respond to request and is unkillable.

Expected Results:  
tvheadend is able to use the dvb adapter and respond to requests.

New bad kernel is 6.3.8-200.fc38.x86_64
Previous working kernel is 6.2.15-300.fc38.x86_64
tvheadend 4.3^20230408gitf32c7c5-1.fc38 from rpmfusion

tuner device is a Hauppauge WinTV-Starburst2 (model 150300, rev C2I9)

I did not see anything wrong in the kernel log, it is the same as the previous kernel
