(In reply to Petr Valenta from comment #11) > Created attachment 876664 [details] > dmesg with kernel 6.10.3 with additional boot paramaters: > acpi.debug_level=0x08000000 acpi.debug_layer=0xffffffff I have attached the required dmesg output with acpi.debug_level=0x08000000 acpi.debug_layer=0xffffffff. There is a interesting consequence of these kernel parameters because after adding these, problem with high cpu usage is gone. With booting without these parameters 1 cpu core is fully utilized again. After adding them back again problem is gone. Thank you for this workaround :)
