I am seeing this problem on a Gigabyte GA-MA74GM-S2 motherboard. I have tried changing the BIOS setting for both AHCI and IDE modes. I get the same error upon boot.
I did a dist-upgrade from Maverick ( 10.10 ) to Natty ( 11.04 ). After the reboot I see this error all the time. However, I also saw this issue before on the same machine with Lucid ( 10.04.2 LTS ).
