Do a workstation need ACPI support in the kernel?

I have Dell Precision T7400 and I am having problems with rebooting, as in it won't.
It gets to "Restarting the system" and then stops; I then need to power off the computer and on again too reboot..

I thing this might have something to do with acpi and was just wondering; do workstations need acpi support or can I just disable acpi in the kernel?

Regards,

BTJ

You don't *need* acpi in the kernel as much as you need your network drivers. :lol:

But you need it for powersaving functions and for things like an automatic shut down.

There's really not a lot of reason to not include ACPI support on a modern system, it encompasses quite a bit of functionality. At the very least, it's probably keeping your computer from actually shutting itself off when you ask it to.

A lot of new systems require ACPI to be configured correctly. ACPI is a lot more than power management.

Ok, thx... I did a quick check with a kernel without acpi stuff enabled and it didn't solve my rebooting problem anyway, so.... :-|

You do have acpid in default runlevel, right? Also, on recent kernels I had to enable all deprecated /proc/acpi options. But then again, I also had troubles with some dell's machines at work...
