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: kernel: klogd 1.4.1#10, log source = /proc/kmsg started. kernel: Loaded 23027 symbols from /boot/sysmap.linux-2.4.25-orig.test. kernel: Symbols match kernel version 2.4.25. kernel: No module symbols loaded. kernel: Linux version 2.4.25 (root-xTE1z6Ssw50@public.gmane.org) (gcc version 2.95.4 20011002 (Debian prerelease)) #3 Mon Feb 23 22:32:44 CET 2004 kernel: BIOS-provided physical RAM map: kernel: BIOS-e820: 0000000000000000 - 000000000009f800 (usable) kernel: BIOS-e820: 000000000009f800 - 00000000000a0000 (reserved) kernel: BIOS-e820: 00000000000ea000 - 0000000000100000 (reserved) kernel: BIOS-e820: 0000000000100000 - 000000000fff0000 (usable) kernel: BIOS-e820: 000000000fff0000 - 000000000ffffc00 (ACPI data) kernel: BIOS-e820: 000000000ffffc00 - 0000000010000000 (ACPI NVS) kernel: BIOS-e820: 00000000fff80000 - 0000000100000000 (reserved) kernel: 0MB HIGHMEM available. kernel: 255MB LOWMEM available. kernel: ACPI: have wakeup address 0xc0001000 kernel: On node 0 totalpages: 65520 kernel: zone(0): 4096 pages. kernel: zone(1): 61424 pages. kernel: zone(2): 0 pages. kernel: ACPI disabled because your bios is from 2000 and too old kernel: You can enable it with acpi=force kernel: Dell Inspiron 7500 machine detected.

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.
