Comment 33 for bug 2049220

I have issue with this fix - my card (Comfast CF-953AX with mt7921u) stopped working running on Ubuntu 22.04 with kernel 6.5.0-18-generic and linux-firmware_20220329.git681281e4-0ubuntu3.28.

Error message as follows:

Reverting to linux-firmware_20220329.git681281e4-0ubuntu3.26 fixes the issue with proper boot log:
