dmesg
Honor MagicBook 14 pro (2025 version) is not correctly detected due to bad ACPI
implementation, there is a lot of errors causing hardware detection issue like
no keyboard (must use i8042.dumbkbd=1 to have it working), no touchpad, no fan
control (nor detection either), no function key (through huawei-wmi) and intel
sound must be tweaked to avoid kernel panic.
Here is the options used to have something working more or less :
i8042.dumbkbd=1 snd-intel-dspcfg.dsp_driver=1
Attached acpidump and dmesg.
Kernel version : 6.15.8
Processor : Intel(R) Core(TM) Ultra 9 285H
