2.4.21-pre4 acpi 20030122 on Toshiba laptop

[Sander Smeenk <ssmeenk-ntXksADE/7Pk1uMJSBkQmQ@public.gmane.org>]

Hi,

I want to let you know what my experiences are with ACPI on my Toshiba
Satellite Pro 6000 laptop. I always had trouble with rebooting, and shutting
down, it just didn't happen.

With this kernel the machine does shut down properly and reboots
properly, so that is fixed now. Better not touch it :p

I tried fixing my DSDT by disassembling it, fixing the warnings that
turned up with iasl, and putting it back in the kernel with the
appropriate patches, but it didn't change a thing, so it seems.
Ofcourse I don't know if I fixed it The Right Way(TM). 

Okay, next I tried 'sleep modes'. Because I want to be able to suspend
my laptop. cat /proc/acpi/sleep displays:
| S0 S3 S4 S4Bios S5

S0     = Default operation, so that works :p
S3     = echo: write error: no such device
S4     = Laptop suspends, wakes up, but after waking up, it hangs
S4Bios = See S4, exactly the same behaviour
S5     = Kernel Oops:

I hope this information helps!
