For more information [1] about 2.6.14 kernels see ;-)

Sounds about right if your CPU clock hapens to be 8MHz so probably not.
Chances the counter was missprogrammed.  Or are you running uncached?
Uncached will completly devastate performance.

At about this point the actual console driver is registered and takes
over from the early console driver - whatever that may be in your case.
So seems the early console driver is fine but the actual console driver
(that is serial driver) is falling over.
