[503] Thu 30.Dec.2004 16:51:10 [kadmin@archangel][~] #sysctl kern.timecounter.choice kern.timecounter.choice: TSC(800) ACPI-fast(1000) i8254(0) dummy(-1000000) Last box I had trouble like this on was K6-2/500 on Asus p5a mobo. Setting to i8254 worked in that case. If you've not tried all the possibilities, do so now. I must also say that I *think* I had a box (around PII 200) that I never got this resolved on (but I'm not sure how hard I tried....) HTH, Kevin Kinsey
