Hi,
I notice a regression report on Bugzilla [1]. Quoting from it:
vmlinuz-6.3.7-200.fc38.x86_64 and vmlinuz-6.3.8-200.fc38.x86_64
in the switch tv channel to another vlc stay blocked and and the loading of firmware newer ending. power must be switch to off. from dmesg:
dvb-tuner-si2141-a10-01.fw dvb-demod-si2168-d60-01.fw firmware version: D 6.0.13
restart of dvb modules is impossible, They stay working.
kernel 6.3.5-200.fc38.x86_64 works OK. I don't how works kernel 6.3.6-200.fc38.x86_64
this same error is in vmlinuz-6.3.5-200.fc38.x86_64 and earliers but there is the occurence accesptable.
listing from 6.3.5 kernel:

?????? The problem in dvb_usb_dvbsky or firmware ?????
The answer from https://bugzilla.rpmfusion.org was:
If it was working with previous kernel this is likely a kernel regression. please forward to the dvb sub-system maintainers.
this problen insist a long time (years), but not too horible
See Bugzilla for the full thread and attached dmesg and lsusb.
Thorsten: The reporter can't perform bisection for he has problem compiling his own vanilla kernel (see comment 8 on the Bugzilla ticket, albeit with translated make(1) output). Can you take a look on it?
Anyway, I'm adding it to regzbot (as stable-specific regression for now):
#regzbot introduced: v6.3.5..v6.3.7 https://bugzilla.kernel.org/show_bug.cgi?id=217566 #regzbot title: switching TV channel causes VLC and firmware loading hang
Thanks.
