The kernel clock seems to be running fast. I rebooted the computer to reset the CMOS clock, but it was correct. I checked the dmesg logs and found that the messages about the TSC counter reported a different frequency every time the computer was rebooted. The other counter, i8254, seems to be stable. Is this problem fixable or is the hardware bad? Thanks for any assistance. ---------- log excerpts ---------- Mar 1 16:52:00 istest1 /kernel: Timecounter "TSC" frequency 180410017 Hz Mar 8 08:55:16 istest1 /kernel: Timecounter "TSC" frequency 158760415 Hz Mar 10 17:32:42 istest1 /kernel: Timecounter "TSC" frequency 155152435 Hz Mar 14 15:38:40 istest1 /kernel: Timecounter "TSC" frequency 150542944 Hz Mar 15 15:47:19 istest1 /kernel: Timecounter "TSC" frequency 173193367 Hz Mar 23 10:26:08 istest1 /kernel: Timecounter "TSC" frequency 169585097 Hz Mar 23 10:28:47 istest1 /kernel: Timecounter "TSC" frequency 155152319 Hz Mar 23 10:36:34 istest1 /kernel: Timecounter "TSC" frequency 155152289 Hz ---------- dmesg output ---------- Copyright (c) 1992-1999 FreeBSD Inc.
