No, I don't use the NMI watchdog...
So the optimization of removing these I/O accesses is bogus for my configuration. Btw. I don't know if I already mentioned it, but I use the VIA KT400 chipset. Maybe this is of interest...
The only way to cool down my CPU was to enable timer_ack.
I don't know how to help you, but of course I am willing to test patches... ;-)
