With no APM in the kernel, the BIOS is not at liberty to play with the clock. (No connect, no enable.) You're welcome to check the archives, if you wish. I also consider it a fault in our timing support if it can't handle time moving forwards at a variable rate. "APM" doesn't send the clock backwards, so no time interval should ever be negative. Please take this issue seriously. You can't just handwave and say "it's all APM's fault". -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
