Message-ID: <1066475780.2607.6.camel@paragon.slim> (raw)
Hi,
With test8 there are still problems with the longhaul cpufreq stuff:
longhaul: VIA C3 'Ezra' [C5C] CPU detected. Longhaul v1 supported.
longhaul: MinMult=3.0x MaxMult=6.0x
longhaul: FSB: 0MHz Lowestspeed=0MHz Highestspeed=0MHz

I'll check if I can fix the min/max freq. Is Longhaul v1 correct for
