I'm fairly sure this is due to broken hardware for the ACPI timer. Atleast I had the same problem with one machine running -current and resorted to using the TSC as a timecounter again too. I don't know if it is a common enought problem that there should be a work around. It may well be worth it to avoid a deluge of complaints when -current becomes -stable. (Mind you, people with broken ACPI stuff will have enough problems when -current becomes -stable anyway.) David.
