Just thought I would share some insight on issues I have had when installing various Linux distros on a computer with a GA-880GMA-USB3(rev. 3.1)motherboard and AMD FX-8150 processor. Using the instructions provided by Gigabyte it was impossible to install Ubuntu 11, CentOS 5 and Gentoo 12. It turns out some issues arise with either the Advanced Host Controller Interface (ahci) or most probably the Advcanced Configuration and Power Interface (acpi). To get any of these distros to boot I need to add the following boot time options: noapic, nolapic and noahci.
This would lead the OS to seeing only one core in the cpu though.
In gentoo I was getting following message before the boot process would freeze: ACPI Warning: Incorrect Checksum in Table [TAMG] (20110623/tbutils-314) - 0xD2, should be 0xD1. It would in fact freeze when loading the achi module.
Finally another workaround for all this was to disable AMD C1E Support in the Bios. No need to add any boot time options and all cores are seen!
The system has the latest bios off the gigabyte website (F4C, still BETA?) and 16GB of corsair RAM. No overclocking.
Any ideas why this might be happening?
Thanks!
