I know this is a bit off-topic for this group, but I need some
serious help, and I'm sure that if anyone can help me they will be a
member of this group.
I have a MacBook Pro that apparently crashes, and my regular bug
reports have not resulted in anything I can do to assist Apple in
tracking down the reason.
My computer is used mostly in a "closed lid" mode, with occasional
use in portable mode. I never seem to have problems with it in
closed-lid mode - its always a result of going to portable mode (ie I
use it untethered).
I am using Time Machine, so before I unplug the computer I unmount
the Time Machine disk, then do a "Sleep" from the finder.
Two events are happening fairly regularly:
1) When the machine gets re-plugged into all the cables needed for
closed lid mode, it never wakes up, and I have to use the power
switch to shut it down for real, then reboot it. When this happens,
the fan is going.
2) Last night, the machine just froze. I was in Xcode typing away
when the trackpad and keyboard went dead. I have the clock in the
menu bar show seconds, so I can see if the Window Manager is running,
but it was stopped too.
Apple had suggested I try to ssh into the machine, which I have, but
its non-responsive (I cannot get a login prompt). When the machine
does reboot, there is nothing in the log - no crash report, nothing
at all. Its like it never happened.

So, the purpose of this post: what else can I do to try and track
down what is going on? Is the some additional logging or reporting I
can enable? Can I build a debug kernel and use it to catch the
problem?
My fear is that this is a Leopard issue - I just never had a problem
in the 6 months it was running Tiger. The problems started happening
when I installed Leopard (fresh install).

PS: I run Permissions Repair and Disk verify all the time, the disk
itself is clean.
