Comment 56 for bug 395239

I hit this issue with ABIT's IL-90MV motherboard. SSDT table is totally busted, and with this obsolete hardware, there is very little chance that the BIOS is updated.
_PST in SSDT has the wrong CPU frequencies and voltage IDs. My 2GHz CPU is showing that the max CPU speed is 1.2GHz.
I did send a "tech support" request to the ABIT.com.tw that Linux does not work too well with such BIOS.
I am hoping that it's fixed in the future, but it's very unlikely because ABIT is not going to make any money fixing the problem.

Meanwhile, there is not much I can do but to get out from Karmic.
Very sad.
