OK. Here's an update. This is some funky junk:

First off, I'd like to note, once again, that APM works PERFECTLY under
Linux on this laptop with a 2.4.18 and 2.4.20 kernel. I could even suspend
and resume from X Windows without problems. FreeBSD's APM code must not
be as mature as Linux's, or Linux's APM code has patches applied to deal
with my (possibly) quirky BIOS.


As I said I would do in my last post, I tried to set:

hint.ata.1.disabled="1"

at the loader prompt to disable the second ATA channel (and my
CDROM/DVD-ROM). This didn't work. The ata1 device was still detected and
my laptop still froze on resume.

But then I had a brilliant idea: Why not remove the CD-ROM drive from the
bay?

So I did. And Lo, it works! I have posted my APM resume log at the bottom
of this message so everyone can see where my system normally freezes.

(All notes are applicable _only_ with the CD-ROM/DVD-ROM REMOVED from the
UltraBay Plus drive bay!)

# -------------------
# When suspend works
# -------------------

1.) When logged into a VTY
2.) The _FIRST_ time I use 'zzz', but all further suspends lock the system.
3.) ANYTIME I use Fn+F4, as long as it isn't preceeded by a 'zzz' suspend
    AND I'm looking at a VTY (as opposed to X Windows).

# -----------------------------
# When suspend locks my system
# -----------------------------

1.) When in X Windows (this never happened in Linux. What gives?)
2.) When I suspend using either Fn+F4 _OR_ 'zzz' after I have used
    'zzz' once. (I think this may have something to do with the
    fact that 'zzz' doesn't sync the disks and pause before
    going into suspend, whereas Fn+F4 does.)


I'm still very interested in getting suspend to work when my CD-ROM is
installed. I can live with the other quirks, but I need my CD-ROM.

Does anyone have any ideas?
Does anyone know how to disable ata1-slave? (ata1-master is my CD-ROM.
Please see previous posts for dmesg.)
