Let's backpedal a bit: looking at trixie's initial release (13.0), we
already had firmware-iwlwifi with /usr/lib/firmware paths, and I'm
*pretty sure* that works fine!
What wasn't mentioned in this bug report is that we're talking about
custom builds, not about official images. (See, that's why you shouldn't
contact individual maintainers directly, and instead include all context
in a public conversation in the first place…)
Are you missing Contents-firmware files, possibly because you're using
an old debian-cd branch, or maybe no debian-cd at all?
If that's indeed the case, the patch is only needed for the fallback
code, so that's less serious than what I thought.
Example with the non-fallback code:
May 22 01:12:42 check-missing-firmware: looking at dmesg for the first time
May 22 01:12:42 check-missing-firmware: saving timestamp for a later use: [ 27.986681]
May 22 01:12:42 check-missing-firmware: looking for firmware file rtw88/rtw8821c_fw.bin requested by rtw_8821ce
May 22 01:12:42 check-missing-firmware: looking for firmware file rtw88/rtw8821c_fw.bin requested by rtw_8821ce
May 22 01:12:42 check-missing-firmware: looking for firmware file rtw88/rtw8821c_fw.bin requested by rtw_8821ce
May 22 01:12:42 check-missing-firmware: missing firmware files (rtw88/rtw8821c_fw.bin) for rtw_8821ce
May 22 01:12:42 check-missing-firmware: mainloop iteration #1
May 22 01:12:42 check-missing-firmware: lookup with /cdrom/firmware/Contents-firmware
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
May 22 01:12:42 check-missing-firmware: installing firmware package /cdrom/firmware/firmware-realtek_20250410-2_all.deb (non-free-firmware)
May 22 01:12:42 check-missing-firmware: modprobe: FATAL: Module rtw_8821ce not found.
May 22 01:12:42 check-missing-firmware: modprobe: FATAL: Module rtw_8821ce not found in directory /lib/modules/6.12.29-amd64
May 22 01:12:42 check-missing-firmware: removing and loading kernel module rtw88_8821ce as well (actual module for rtw_8821ce)
In your case I'm assuming you're getting *without* there?
Cheers,
