next in thread | raw e-mail | index | archive | help
I am running the 4.3-BETA (though the same were true for 4.2-STABLE) with a
new Intel 815E EAL motherboard and trying to get APM functioning with
interesting results. The machine will freeze up early in the boot sequence
on normal boots (look for the (freeze) below to see where). However, if I
use 'boot -c' and 'ls' followed by 'quit' inside the config utility, it
boots normally (and APM works fine). Why would using 'boot -c' make a
difference for APM?
Below are the results of a 'boot -cv' with the '(freeze if no -c given)'
added where it freezes if '-c' isn't given on the boot command. This
kernel is also compiled with -DAPM_DEBUG.
