Well, after much tinkering and tweaking, the verdict is still the same. ACPI
unusable for my IBM A30p (1.16 BIOS) with FreeBSD 5.0-RELEASE.
Furthermore, if I shut off ACPI at boot time using:
The kernel locks up (freezes. nothing happens. No DB> prompt.) right before
the keyboard controller. Thus, I cannot use APM either.
My 4.8 kernel wouldn't even detect APM at boot time (yes, it was compiled
In addition, 5.1-BETA and 5.1-BETA2 both panic on boot of the generic
install CD kernel, so I can't very well test out the newer ACPI support and
see if it's
I really need some kind of power management support if I'm going to do any
of usefull work on this laptop. Therefore, I think I'm going to have to give
Linux a try.
Perhaps linux's kernel won't detect APM and won't support ACPI either, but
three different websites that claim working APM support under linux for the
(Granted, I most certainly have a newer BIOS than they had when they wrote
pages, but it appears that Linux is my last chance for working power
a UNIX-like OS.)
Anyway, it appears to me that 5.x has a long way to go before it's of the
as 4.x. On my servers and even on this very IBM A30p laptop, 4.x hasn't
given me a
single panic, crash, or other failure. (But I don't want to run 4.x because
detect an APM device)
I sincerely hope the FreeBSD programmers can work all of this kernel
quickly. The new 5.0 feature list looks very appealing! But I for one won't
run 5.x until
it starts living up to the legendary BSD reliability. Good luck folks.
You've got your work
cut out for you.
If anyone wants any additional info about my box, or would like me to do any
testing, then I'm all for it. Just let me know what you need from me. In the
I'll be installing Linux, I think.
