zzz generates "Inappropriate ioctl for device" as do all other apm
commands.
apmconf -e generates "can't ioctl APMIO_ENABLE"
me thinks something is wrong in the kernel support for apm, but i
double checked that apm support was compile in. i even rebuilt the
kernel to make sure.
system:
quantex h1331 p2 233
freebsd 2.2.7 + pao
what's the best way to troubleshoot this problem?
Well, for starters, I'd fix apmconf to tell you something better than
"I can't ioctl." Patches (for 3.0 or therebouts) are attached. Could
someone commit this if appropriate?
Offhand, my own scientific wild-ass guess is that you have a binary
incompatibility between your apm software and your kernel. Did you
PAOify apm and apmconf when you PAOified your kernel?
