Don't know if this is any use in debugging, but a recent adventure in trying to cvsup to 6.0-stable (story for another day) left me doing a iso install back to 5.4. I noticed that the 5.4 install from the original 5.4 release cd did not have this problem. It was only after i CVSUpped from the 5.4 cd install to the most recent 5.x that the problem reappeared. Don't know what changes happened in acpi through the life of 5.4, but it may be of some value. Interested in solving this also. apm allows me to keep the laptop on battery, but i get: apm: can't open /dev/apm: No such file or directory on any usage. regards, Brad On Thu, 10 Nov 2005, Sam Leffler wrote: > I've got an nx6125 running amd64 current.
