I spoke too soon. I think I may have been booting back to 211813 which was never removed from kernel.old. I should have been renaming whatever kernel build to /boot/kernel.r21XXXX instead of relying on that mechanism. In other words periodic=1 did not work for me, but changing the timer selection did. I left kern.eventtimer.perdiodic="1" in /boot/loader.conf and also changed kern.eventtimer.timer="LAPIC" to boot up. I have not played with running through all the different combinations, but this allowed be to boot r213481 from this morning. I'm assuming it's choosing the HPET timers. kern.eventtimer.choice: HPET(450) HPET1(450) HPET2(450) LAPIC(400) i8254(100) RTC(0) kern.eventtimer.et.LAPIC.flags: 15 kern.eventtimer.et.LAPIC.frequency: 100005979 kern.eventtimer.et.LAPIC.quality: 400 kern.eventtimer.et.i8254.flags: 1 kern.eventtimer.et.i8254.frequency: 1193182 kern.eventtimer.et.i8254.quality: 100 kern.eventtimer.et.HPET.flags: 3 kern.eventtimer.et.HPET.frequency: 14318180 kern.eventtimer.et.HPET.quality: 450 kern.eventtimer.et.HPET1.flags: 3 kern.eventtimer.et.HPET1.frequency: 14318180 kern.eventtimer.et.HPET1.quality: 450 kern.eventtimer.et.HPET2.flags: 3 kern.eventtimer.et.HPET2.frequency: 14318180 kern.eventtimer.et.HPET2.quality: 450 kern.eventtimer.et.RTC.flags: 17 kern.eventtimer.et.RTC.frequency: 32768 kern.eventtimer.et.RTC.quality: 0 kern.eventtimer.periodic: 0 kern.eventtimer.timer: LAPIC kern.eventtimer.idletick: 0 kern.eventtimer.singlemul: 2 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkysj/UACgkQrDN5kXnx8yZSDQCbBrc5gFHhDfBi4pncbzKobNIo 8X4AnRD4QIWaPqQy8R+Blf2Fy82HCiIr =ZUPH -----END PGP SIGNATURE----- _______________________________________________ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
