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. I get this problem on my system board as well.
I've pasted the relevant dmesg output
I can also note that this problem is still prevalent in the kernel as of

I've left it all in in the event some of the later hardware issues (near =

end) is part of this problem. Either that or this system board is a real=

flawed design.
FYI, I'm having the same problem on an ASUS P5A, BIOS 1011 BETA, K6-2 500Mhz. Setting kern.timecounter.hardware to TSC seems to have solved the problem. Cheers, Jason One more thing: I'm running 5.1R. The problem did not occur under 4.6R, 4.3R, or 3.2R on the same machine. Don't know if it matters, but I did upgrade the BIOS from 1007 ro 1011-BETA at the same time I upgraded to 5.1R. ( Had to to get my 80 gig IDE drive recognized ) Cheers, Jason State Changed From-To: open->closed Using the TSC works around the problem, which is believed to be due to broken hardware |
the time of day clock runs fast. For example: $ date; sleep 5; date Fri Nov 23 14:12:55 GMT 2001 Fri Nov 23 14:13:05 GMT 2001 $ sysctl kern.timecounter.hardware=TSC $ date; sleep 5; date Fri Nov 23 14:13:17 GMT 2001 Fri Nov 23 14:13:22 GMT 2001 In both cases, the subjective time was 5 seconds.
