I think I found the problem, and being able to work around it.
But, I don't know how to realy fix it.
Here's summery of what was happening...
1. APM fails if randomdev_load="YES" in loader.conf and ACPI configured.
Some drivers' probe & attach order will change, if randomdev module
was loaded using loader.conf.
I have ACPI test driver (as of early May) and APM driver in my kernel,
that was affected by this change.
1)Randomdev NOT Loaded: Probe & attach will happen in the order -
(1)nxp0, (2)apm0, (3)acpi0 .....That's OK
2)Randomdev Loaded: Probe & attach will happen in the order -
(1)acpi0, (2)apm0, (3)nxp0 .....NG
Because acpi0 access the BIOS first, APM support in BIOS seems to
get turned off. :-(
If there's any way to statically set the probe & attach order, I would
like to know.
2. Work around was to include RANDMDEV in config file.
I disabled it, because it was panicing on shutdown.
That being fixed in rev1.5 of randmdev.c, I have a working system, again.
Thanks you,
Haro
