Subject: AX200 cards broken after firmware cc-a0-67

Hello,

I own 3 boxes with AX200 cards, one is a Killer AX1650x, the other two
AX200 [8086:2723] (rev 1a).

After commit 4474519a1fd4e7167afae7c5ca2c1b93e17b4d8a in
linux-firmware tree, which updates
the firmware to cc-a0-67.ucode, all cards are crashing with microcode
errors. Firmware  cc-a0-66.ucode
is still fine. The kernel doesn't seem to matter, as soon I update the
firmware to >=67 ( I tested 68 too ),
everything crashes in an endless loop.

I'll attach a dmesg, from 5.17.0-rc2, the same crash happens with 5.16* etc.

Please CC me.

Best regards,

Gabriel
