(usb people, issue 1 is partly relevant and issue 3 is definitely USB.)
I have been testing my test10 installation and have come up with
a few old problems, all of which have been reported before.
1. Warm reboot fails to restart, i.e. hangs after displaying 'Restarting
system'. In this particular scenario, the power switch is disabled
too and the only way in which the machine responds is by switching
off at the wall and pulling the battery. Note that this scenario has
been
observed only if I boot, get the login prompt (optionally log in)
and then
ctrl-alt-del. A similar scenario occurs after an amount of time
using the
machine and then rebooting. In this case, the machine restarts
successfully
but hangs when it tries to initialise (right word?) the UHCI
controller.
Here is the exchange Randy Dunlap and I had about this some
(internet) time ago:

Richard,
I have that same USB host controller in my PC (not laptop).
I have built usb-uhci and uhci-alt (which Richard is not using
BTW) into the kernel (2 separate kernels of course) and
rebooted with both of them successfully.
Can you provide a kernel log up to the point of the failure?
Maybe there's something other than USB that's locking up,
but it appears that it's the USB UHCI HCD that's the problem
because that's the latest info on the console.
Or does usb-uhci actively complain about a problem?
My experiments didn't work, so I'll try just thinking
about it... The usb Makefile and module inits did change
recently. Maybe that has something to do with it.
I'll keep thinking/checking on it.

I thought that it had been fixed, but I was wrong.
2. Parallel port cdrom fails to mount disks:
modprobe friq
modprobe pcd
mount /dev/pcd0 /mnt/cdrom fails with a return code of 32.
Additionally, lsmod after the aborted mount shows that the following
modules
have been unexpectedly loaded: nls_iso8859-1, nls_cp437, vfat and
fat. Note
that the cd is an iso9660 formatted disk.
Here is the relevant section of my log file:

3. usb-storage: I am using a LaCie USB hard disk which generally behaves
perfectly well.
In one situation, though, I have problems. I unmounted all the
partitions on the USB
device manually and then issued the 'halt' command. During shutdown,
towards the end
where usb-storage is removed (or something similar - I forgot to
bring that bit of the log file )-8 )
I see reams of
usb-storage: *** thread sleeping
messages which, in fact, never stop. The only recourse is the power
switch.
Thanks for listening,
Richard
I currently do not use either APM or ACPI. Initially I used ACPI
and removing it in test8 appeared to fix the problem (but I suspect
that was just 'appear' rather than 'fix' 8-). I moved to APM instead
of ACPI in test9 - no change, and indeed in test10 I use neither.
There is a flag in the BIOS for Plug n Play OS. I shall toggle it and
observe the results.

I have seen this with my IBM Thinkpad 600E several times.
Many (newer, at least) IBM machines I've seen will power down if you hold the
power button down for 2-3 seconds. Try that instead of pulling the plug and
battery.
It may be true for other machines also.

The power switch is totally unresponsive in this situation.
