REQ HELP: Intel D865PERL board, 2.6.x kernel, runs like a 386 when running with ACPI?

Hi all....

I have been at this for weeks now. Please help. Im pulling my hair out. :-)

* If you want to reply, remove the underscores in my address.

I have tried to get onto the 2.6 kernel (tried with 2.6.1, 2.6.3 and am
currently on 2.6.4 with the problem still apparent).

Its basically running great with the sound working, LAN, graphics etc. except
for a few problems that seem to relate to ACPI from what I can see or it may be
to do with the motherboard. I have it setup as a software RAID-1, and that is
working great.

If I boot with ACPI=off in /etc/grub.conf, it boots and runs quickly. BUT, if I
run with acpi enabled (i.e. acpi=force) it runs like a 386 and takes forever to

In addition, with ACPI off, when I come to shutdown and power off, it hangs the
system at "System halted". I then have to physically switch the machine off.
Under 2.4 this machine powers off ITSELF. I dont need to hit the switch with my
finger. The machine also turns off ITSELF after shutdown if I suffer the
machine running like a 386 with ACPI enabled.

[1] My assumption is that I cant have the best of both worlds - its either ACPI
off with a fast machine but manual power-off


[2] ACPI on, runs like a slow 386 equivalent machine, but shutdown powers off
properly. It takes AGES to boot up when I run it with ACPI!

Obviously, option 1 is the clear winner here, but it would be great to get to
the bottom of this.

I have rebuilt the kernel with highmem support, ACPI and / and APM (to try to
cure the shutdown / poweroff glitch) - I tried using either / or. This is no
good and I get either the slow machine syndrome described above, or a fast
machine with no acpi and manual power off.

I have the libata and ata_piix (version 1.01) in the kernel - these show in

In short, I want ACPI working and my machine running at its proper speed and a
proper shutdown without the need to flick the power switch myself.

In Windows mode (not that I use it!!!) it runs quickly with no problems so I
think there are no IRQ / hardware problems.

Thanks in advance for any help with this.

1. Help with root on my 386 running System V

I recently purchased a 386 running AT&T UNIX System V for 10 bucks...While I
know the password to access the Audix voicemail system, I can't get root

What are my options for getting acess to root? do I need to reinstall UNIX?. If
so, where can I get a copy of System V for very little or for free?(no manuals
needed, I have those)
