I certainly didn't expect the >removal of apm to mess up the timecounter. Are you sure you don't have APM enabled in the BIOS ? Having apm in your kernel should not affect the timecounting unless it manages to attach to the APM bios, in which case the i8254 is used rather than the TSC for timecounting. That would explain you "factor 32" thing as well, your APM bios is slowing your CPU to save power... -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
