On my new PC something is wrong with ACPI support under Linux. I have to boot it with acpi=off and nolapic. Also it detects only one CPU core (this annoys me the most) and won't shut down completely, I have to hold power button for few seconds to power PC off.
The question is: what can I do? Edit some config files? Report bugs? Send mails to motherboard manufacturer? Run some utility to help reverse-engineer drivers? (Currently I just turn AMD C1E off in BIOS. It's a nice workaround.)
My configuration:
- Ubuntu 12.04 (upgraded from 11.10)
- Processor AMD FX(tm)-4100 Quad-Core
- RAM 8,00 GB
- Graphic Gigabyte GV-N56GOC-1GI (NVIDIA GeForce GTX 560)
- Mainboard Gigabyte GA-870A-USB3
- Disk ATA OCZ-AGILITY3 (SSD)
