System is a Debian 11 amd64, kernel 5.10.201, DVB-T board is an Hauppage
WinTV-quad.
It happens with every kernel version tried, 4.x, 5.x, 6.x.
If a DVB-T streaming is being played (i.e. I'm watching TV channels in
Kaffeine) and I suspend to ram with /usr/sbin/pm-suspend, when system
resumes DVB play is unable to continue.
Closing and reopening kaffeine doesn't help.
The only thing I can do, then, is:
-close kaffeine
-rmmod cx23885
-modprobe cx23885
I attach a boot dmesg, a suspend / resume without DVB play, and another
with DVB play active.
