My machine had two SATA 300GB drives
(WDC WD3200KS-00PFB0 21.00M21) one carrying FreeBSD RELEASE-6.3
and the other RELEASE-7.0 all of which worked OK.
Recently added SATA 1TB (WDC WD10EADS-00P8B0 01.00A01) and
installed RELEASE 8.0 thereon. When I boot to RELEASE 8.0
I find after some time, few minutes to rather more minutes
the system just powers down without warning or any obvious cause.
It seems to mostly happen when the system is relatively quiet.
Suspecting the ACPI I added:
hint.acpi.0.disabled=1
to loader.conf.
I then found RELEASE 8.0 would not boot -- or at least
it was unable to mount root. I get a "mountroot>" prompt
but this seemed not to accept anything I could think of,
and "?" to list available targets yielded nothing. Rebooting and
overriding this with option 2 (enable ACPI) in the boot menu
took me back to a bootable but fragile system.
Changing the loader.conf entry to:
debug.acpi.disabled=all
had the same effect as the hint.acpi.0.disabled=1.
I then thought to be somewhat selective with debug.acpi.disabled
and intended to try:
debug.acpi.disabled=acad button cpu lid thermal timer video
only now as I write this I discover I actually entered:
debug.acpi.disabled=acadbutton cpu lid thermal timer video
Now the RELEASE-8.0 booted but remained fragile.
I've repaired this last entry and will proceed to try it.
Meanwhile I feel I am fumbling about in the dark without
sufficient (or any real) knowledge of the range of tasks
performed by ACPI.
Is my guess that I have an interaction problem between ACPI and
RELEASE-8.0 a reasonable one? Where can I go from here?
The system uses a Gigabyte GA-M55SLI-S4 mother board and the
prcessor is AMD Athlon(tm) 64 X2 Dual Core Processor 5600+
Please offer suggestions or comments.

You're quite right, of course. It's a huge job, and I'm not sure I can
do it; just picked up the latest chapter.sgml for another look. I know
I should STFU or fix it, but I can't help at least warning people who,
unless they're at least familiar with ipfw(8), are going to be either
put off or - in my view - misled or confused.
I'll see if I can't come up with at least some updates and corrections.
Thanks for the kick :)
cheers, Ian

Google mains USB charger :)

Most households build up a store of old power supplies from defunct or
lost equipment.
Or even use the 5

Only go this way if you know what you are doing...

most perl scripts begins with
#!/usr/bin/perl
this is common convention (also outside *BSD world)

I've been doing searches for online schools that teach FreeBSD. I've been trying to learn on an off for years but when it starts getting complicated, I get stuck. The handbook don't do allot of good.
My goal is simply this. I want to open a small business, A server, To lease out web space, domains, etc etc. I want to start small and possibly expand to a rack of servers and so on.
I've been searching all say and cannot find ANY online schools that teach FreeBSD. From what I understand, FreeBSD is the best for security and control. I'll be leasing out shell space too so I need security like sh3lls.net. A company like that is eventually what Id like to accomplish. But I need to know the ground up. I don't want to trust an employee with root access to my server.
I remember seeing a book out there specific to what I'm trying to do.
Anyway, I hope you can hook me up with a school. Or the proper books anyway. FreeBSD for dummies or something.
You guys do excellent work. I hope not only to learn but someday contribute back to the freebsd community.
Thanks for you're time.

In fact, it's the recommendation from the original Camel book in 1990
(which I wrote, but the kids forget that :) that no matter where you
install Perl, you always link/symlink /usr/bin/perl so that scripts can
safely use shebang.
