Sometimes, when I reboot my laptop (Thinkpad T61 running amd64-4.99.54 at the moment), the kernel doesn't detect speedstep. If I try to run estd, I get estd: Cannot guess CPU-scaling technology. (maybe you are missing some kernel-option?)Similarly,$ sysctl -a|grep freq gives no output. It isn't a kernel build option; a reboot will usually bring it back. I've attached /var/run/dmesg from the last boot.
When it fails are you booting with the AC adapter unplugged? If so: http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=38360 Jared
