The TSC is unlikely to work with more than 1 active CPU. Both the i8254 and ACPI-notslow work OK for me, but very slowly (time for reading the counter: i8254: 4-5uS; ACPI-notslow: 1.6-1.7uS). > Just constantly moving mouse (touchpad) in X also helps. I have an nfs latency problem where pinging the interface to keep it active helps a lot. Both behaviours would be explained by interrupts are getting lost somewhere. Bruce
