The code we have messed w/ so far is according to AMD 0fh family BKDG. Best Regards, sephe -- Tomorrow Will Never Die

It prints a lot of error like: "cpu0: Invalid FID" "cpu0: Invalid VID..." The last two lines it prints are a bit different: "cpu0: min VID mismatch real 9, lim 11" "cpu0: min FID mismatch real 50, lim 6" Cheers, -- Maurizio Lombardi

My K8 box needs that for it's messed up FID/VID. See http://bugs.dragonflybsd.org/issue2025 cheers, Max

The last patch triggered others errors like the following: cpu0: Invalid FID 0x20, out [0xe, 0x16] cpu0: Invalid VID 0x6, in [0xd, 0xb] I modified your patch to force the kernel to ignore those errors: http://www.dotter.it/~maurizio/acpic5.diff But the kernel freezes at boot when it tries to initialize the cpu driver -- Maurizio Lombardi
