For some reason, the RTC stops sending the 128Hz statclock (statistics clock) interrupts.

APM however is a known culprit for causing badness here. > On Mon, 26 Aug 2002, Lars Eggert wrote: > > > Patrick Thomas wrote: > > > Now, when I repeat vmstat -i, all of these numbers (or rather, all of the > > > large numbers) increase _except_ for `rtc irq8`. > > > > interrupt total rate > > mux irq11 4851 12 > > ata0 irq14 94219 240 > > atkbd0 irq1 399 1 > > fdc0 irq6 2 0 > > ppc0 irq7 1 0 > > clk irq0 39123 100 > > Total 138595 354 > > > > "Large ones" increasing, too, but I don't seem to have rtc. > > > > > Further, regarding the APM conjecture, this is a server and (although I > > > may be mistaken) does not have APM in the bios at all - I have also > > > removed it from the kernel. dmesg tends to confirm the absence of APM. > > > > Mine's a laptop with APM enabled (BIOS + kernel). > > > > Lars > > -- > > Lars Eggert <larse@isi.edu> USC Information Sciences Institute > > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-hackers" in the body of the message > Cheers, -Peter -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com "All of this is for nothing if we don't go to the stars" - JMS/B5 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
