Revision 0x00000122 for 06-b7-01 (i9-14900HX) breaks initialisation of mei_me #76
Description
Dear all,
I'm seeing a difference before and after updating the microcode for 06-b7-01. I don't quite know what it means, but I do see a multi-second stall on boot when the MEI initialisation fails. This happens even on the same kernel with and without the dis_ucode_ldr kernel option.
