After reading a few articles
(https://bugzilla.redhat.com/bugzilla/long_list.cgi?buglist=17841) and
(http://www.ibiblio.org/pub/historic-linux/distributions/redhat/4.2/i386/live/usr/man/man7/bootparam.7)
for instance. I have tried the following additional changes...

Disabled LCD Screen Expansion in the BIOS - then tried a normal boot + reboot,
and a boot with "reboot=warm,bios" - both failed.
I then tried warm,bios and cold,hard with LCD expansion turned back on - same again.

I have noticed that if I don't pass these additional kernel parameters, usually
the laptop says "rebooting..." then hangs, but the screen stays on. If I pass
seemingly any combination of reboot=x,y .. then the machine says rebooting...
the LCD goes off... and it then hangs.

Shutdown has worked twice now, where as before this would fail too. It does
however, take a good few seconds before it actually powers down the machine.

It might be worth me mentioning that I disabled networking (by removing the
/etc/rc*.d symlinks) for this testing, so there's no Centrino Wireless Weirdness
being loaded at startup, which I wanted to rule out!

Good news is, with the new kernel, shutdown appears to be slightly more stable
(fingers crossed), but reboot hangs consistently.

Hope some of this might be of use...

Mark
