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

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.
