I had a similar problem, which went away when I added these } options to the kernel config: } } options CLK_USE_I8254_CALIBRATION } options CLK_USE_TSC_CALIBRATION I tried adding these options, but it unfortunately didn't help. Now the CPU is being reported as running at 18.08 MHz. I have played around with some of the Cyrix-specific options in LINT that are not noted as being dangerous, but nothing is helping. :( What I really don't understand is how GENERIC works fine with no extra options. I must be missing something simple... -Patrick Patrick L.
