enabled HPET makes LPC bus errors for SB7x0 chipsets


Windows 7 can not write FDD (XP does, but do not use HPET) for the SB7x0 chipsets. People say (;a=commit;h=73472a46b5b28116b145fb5fc05242c1aa8e1461), that it is probably HPET issue and it is required to disable HPET while LPC in work.

Is it real hardware error for SB7x0/SB8x0 chipsets or the Windows 7 can not work with the hardware? Any ideas to combine HPET and LPC bus?
