With latest update from atheros firmware, the wifi stopped working completely. I believe the relevant output for dmesg is:

It also does not work with the firmware from unstable (maybe the device is too new?) but it used to work with some version from experimental.

Actually, wifi does work with the version from unstable. I think I had to downgrade the whole firmware-free/non-free to unstable to make it work again.

(This file was never included in the package, so these messages don't
seem to indicate a regression.)

Other firmware files under ath12k/WCN7850/hw2.0 changed in upstream
versions 20250509 and 20250613.

Can you please test version 20250509-1 (from snapshot.debian.org) so we
can tell which of the 2 updates broke this?

Also please provide the output of "lspci -nnvv -s 0000:c2:00.0".

Ben.

20250509 also does not work. Note, I simply updated the single firmware-atheros_20250509-1_all.deb and not firmware-nonfree etc so it
did not trigger the initrd update. I don't know if this is relevant here
so I mention it just in case.

Also please provide the output of "lspci -nnvv -s 0000:c2:00.0".

Sure thing, see the attachment.


Thanks for taking care,

Bastian

Hi all,

Debian received a regression report for a recent update to the WCN7850:

(Debian applies a patch that adds the "firmware: failed to load" log
