#89652 — Bug#1118199: firmware-mediatek: mt7921e stops working with latest version (20250917-1)

Package: firmware-mediatek
Version: 20250917-1
Severity: normal

Hi,

My wireless driver mt7921e stops working with the latest version of the
firmware-mediatek package. Downgrading to 20250808-1 makes it work again.

I see these errors in the kernel log:

#89728

Package: firmware-mediatek
Version: 20250808-1
Followup-For: Bug #1118199

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   upgrading system as usual, with an upgrade of the firmware-mediatek,
   which led to the wifi chip not showing anymore in the list of network
   devices
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     I did downgrade firmware-mediatek to its previous version, rebooted
     and got back the interface

   * What outcome did you expect instead?

*** End of the template - remove these template lines ***
