Laptop does not reboot

[Dieter Rohlfing <u490248-uKKRHEr75Vc@public.gmane.org>]

Hello everybody,

I already posted my problem to debian-laptop (without success), but
somebody suggested to post it on this mailing list. So, here I am.

My laptop: Dell Inspiron 7500, BIOS revision A11, power management
disabled.

Linux: plain kernel 2.4.25 without any patches, Debian Woody 3.0R1

I installed Debian Woody 3.0R1 one week ago and - as far as I can see -
the system works. Before I had Debian Potato 2.2R4 (plain kernel 2.2.20
without any patches, both acpi and apm off).

My problem: the laptop does not reboot. When I request 'shutdown -r',
the system terminates all applications in my current run-level, properly
runs through run-level 6 and as last message it says 'rebooting ...'.
Then the LED of the built-in CDROM blinks, and the backlight of the LCD
goes off.

Up to this point everything is normal and the same with kernel 2.2.20.
Under 2.2.20 - when the laptop is rebooting - the backlight goes on
after 2 or 3 seconds, the BIOS info screen appears and then my lilo boot
menu comes up.

Under 2.4.25 nothing happens: the backlight stays off, the power LED is
on and the harddisk is still running. The laptop doesn't react on any
key, not even the famous ctrl-alt-del. Unfortunately, the laptop doesn't
have a reset button. :-(((

The only thing I can do: permently push down the power button for about
15 seconds, then the laptop goes off. After a short period I can push
the power button again, and then the laptop begins to boot.

Here is, what dmesg shows about the booting process:

I've deleted the remaining lines, because I think it's not relevant. As
you can see, I played with some kernel options. Among those were:
acpi=on/off/force/ht, apm=on/off, reboot=[cbhw],
pci=bios/nobios/conf1/conf2/nosort/biosirq/noacpi. But whatever
combination I tried, I never had success with rebooting the laptop. The
only way to get a working reboot is with a kernel 2.2.x. Other 2.4.x
kernels (x=18,20,22,24,25) always failed to reboot the machine.

I hope, you can help me. If you need any further information, please ask
me. TIA.
