tv card firmware

I do most system management on a text screen console, and am constantly plagued
by the appearance of a firmware loading message for dvb-demod-si2168-b40-01.fw,
which is needed for my tv usbstick. I do not understand why this firmware should need to
be reloaded regularly every few seconds. I have set it up for loading in my kernel
under 'Firmware loader' ( kernel-6.6.5-zen1, but is was the same under previous kernels)

Can anyone explain why this should happen, and what I am doing wrong if it should not
happen?

Try configuring your tv usbstick driver as a module (=m) not innate in the kernel (=y) and please stop loading the firmware via the kernel.
Rebuild and reinstall the kernel and modules.
Look also in dmesg for firmware loading issues.
If you choose to have a driver in-built in the kernel then have its firmware also loaded by the kernel.
If as a module then don't use the kernel to load the firmware.

My apologies for this late response to your entry, but I did not get the usual email notification that
there had been an entry to my query.

Yes, the problem seems to have been that I had set my kernel to load the firmware. this was necessary
in the past, but it seems not now to be required.

Problem soved.
