Hello,
I would like to experiment with disabling the C-States on the AMD version because xen does not supports them and I suspect some side effects (PM, and touchpad IRQ wake up).
[ 2.150705] [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0)
[ 2.150743] ACPI: \_SB_.PLTF.C000: Found 3 idle states
Could it be possible to add C-state support option in the BIOS ?
Thanks
