Li, all, Just an update: I've successfully changed to ON 111b. This does fix the krtld issues and the special kernel does boot. - I've done testing on an AMD X2 - but since its multi core but not hwpstate and I disabled the check for hwpstate - the kernel crashes (AMD specifically states that TSC change should not be done on a multicore). I now know why ....Note: I had to change a buggy motherboard by a new one to get to this point. - I'm waiting for a colleague to do further testing on a old, single core Intel (he uses the previous version). - I need to upgrade my VIA system to to further VIA testing.
A side question: AMD states that HPET should be used over TSC (see http://marc.info/?l=linux-kernel&m=113112235513757&w=2 - there are more sources). The motherboard has an option "enable HPET". I do not see any support for HPET in the code. Am I missing something? Regards, Tom.
