But I have one Intel(R) Pentium(R) D CPU 2.8 on a VIA8237
My latest suspect of the root of the problem of my computer is not in
Processor but in those VIAs. As you find that "don't provide an entry to
the HPET timer on acpi tables" it match, but how do you know that ?
I don't send DSDT on bugzilla

I try your patch and it give me this differences on dmesg (file attach),
detect a different timer.c but no improvement without notsc boot option
and with notsc the computer got worst.
