If you could share the full URL, that'd be nice to have.

Thanks for the report.

The firmware lookup (in general) seems to be working given:

Looking at a recent trixie-based debian-cd build, firmware-cirrus is
indeed spotted in the list of firmware packages, but there's no
*.patterns file built for it. It ships metadata:

  /usr/share/metainfo/org.debian.firmware_cirrus.metainfo.xml

so that should make its way into the dep-11 thing, but checking what we
do with such information in debian-cd, it's about extracting modalias
information, while that file only lists firmware files (checked in
unstable).

Loop += debian-kernel@ for input.

That means the modalias code path cannot do anything there, but the dmesg
one might have spotted missing firmware files if they were mentioned in
the kernel logs. I suppose that'd depend on whether the relevant modules
are indeed available in whatever image you used, if they were loaded, if
they requested firmware files, if that generated kernel logs that the
installer could pick up, etc.

Attaching a compressed /var/log/installer/syslog might shed some light.


Cheers,

All right, thanks.

Perfect, thanks.

That confirms there's no mention of cirrus thing in there, so the
installer code looking for missing firmware in dmesg cannot work.
Coupled with the lack of modalias information in the firmware-cirrus
package, I don't see how the installer could do anything about it.

Tempted to call this a firmware-cirrus bug, and I'm happy for the kernel
team to steal this bug report away from us if they agree.
