Try disabling C-states if they are enabled. If you have a BIOS option for C1E you might need to disable that as well. If this fixes it, then there isn't a really viable solution in software, and you might prefer to use the RTC to get the power savings from C-states. -- John Baldwin _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
