Do you might sharing which kernel switches you had to enable and which kernel version?
Did you also have to update all the /usr/lib/firmware/ and if so did you use the 20231111 or 20231030 set?
I have tried many variations and mine will not suspend. It suspends but then immediately resumes.
Do you have this masked or disabled?
cat /sys/firmware/acpi/interrupts/gpe1A
Any changes to the BIOS settings?
Trying to isolate a baseline of what is working.
I can start a new thread too if you dont mind me bothering you. I tried many variations of BIOS settings, kernels, and parameters but I have not had luck with suspend. Everything else seems to work perfectly.
