Hoi,

Severity: normal

Just to confirm, which linux version was this tested against?

The current kernel from sid: 6.8.9-1
I've used a locally built live image based on sid (live-build) with the patched hw-detect.

I have an USB wireless adapter that uses the r8712u kernel module and
that requires firmware from non-free-firmware.
...
I see that's a module from staging, maybe it's not behaving like it
should? At least differently from other modules…

As far as I can see, r8712u entered staging in 2012 and has been there since...

I spotted 1422b526fba994cf05fd288a152106563b875fce that fixed a race
condition regarding firmware loading (fix available in v6.6-rc1 and
v6.1.52), maybe there are other similar issues?

In which repo can I find this hash value?

When I disconnect the adapter and reconnect it, the installer is able
to use the adapter properly.
...
I tried several options, but could not get them to work
...>> Do you know a solution (apart from a physical reconnect)?

I'd suggest a search in upstream bugzilla and mailing lists.

I'm adding the kernel maintainers in copy, in case they have better
ideas.

Thanks. I'll try to look some more.

With kind regards,
Roland Clobus
