Here are the last lines from my kernel log: kernel: unloading PCMCIA Card Services kernel: Kernel logging (proc) stopped. kernel: Kernel log daemon terminating. The last message on the console is 'rebooting system ...'. That's all and then the lights went off. As far as I can see the shutdown process comes to a complete end. On booting the next time there's no fsck'ing because of unproperly unmounting. > I presume that if acpi=off doesn't work, then acpi is exempt from > any accusation. :) Sorry, but I do not agree. Suspending and power management is one side of ACPI, but ACPI is also used to setup und configure the system. As far as I noted, the kernel still uses some ACPI information to setup up the system, even if you have 'acpi=off' on your command line. In the case of 'acpi=off' you definitely have no suspend possibilities. As Bernd Schubert suggested, I'll give kernel 2.6.x a try. In regards to PCI kernel 2.2.x had a very 'simple' approach (compared with 2.4.x). 2.4.x makes a better job. But with my Dell I7500 it broke something (okay, I admit the I7500 has a broken BIOS, too). My only hope is that 2.6.x corrects what 2.4.x didn't achieve.
