Hi, Sorry, what, I'm confused. > it will not even try to load next working QuZ-a0-hr-b0-74.ucode That's intentional... We released -77 firmware for this device in 2022, a little over two years ago. We can't and won't support ancient firmware *forever*. We've already supported it for a very long time. > either direct loading or with included firmware in kernel > ("CONFIG_EXTRA_FIRMWARE="i915/tgl_dmc_ver2_12.bin intel/ibt-19-0-4.sfi intel/ibt-19-0-4.ddc iwlwifi-QuZ-a0-hr-b0-77.ucode" > caused kernel reboot) and that kernel 6.4.X could load > firmware direct or included. I have no idea what might be the issue here. Perhaps your kernel ends up too big for the way you're booting it? If you insist on booting without initramfs but with iwlwifi built-in, you need to debug and fix *this*. Or I guess you could always try probing/binding the driver again after the system really boots. > vanilla kernel from 6.11.9 log: > [ 1.903903] Intel(R) Wireless WiFi driver for Linux > [ 1.904006] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002) > [ 1.906832] iwlwifi 0000:00:14.3: Detected crf-id 0x3617, cnv-id 0x20000302 wfpm id 0x80000000 > [ 1.906890] iwlwifi 0000:00:14.3: PCI dev a0f0/0074, rev=0x351, rfid=0x10a100 > [ 1.906891] iwlwifi 0000:00:14.3: Detected Intel(R) Wi-Fi 6 AX201 160MHz > ... > [ 1.907036] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-77.ucode failed with error -2 but I guess that's when you try to have wifi built-in and no firmware built-in johannes
