I have a Dell inspiron 8500 with the gentoo-kernel and I get a kernel oops when booting if I enable acpi.

Is there any patches to get this working?

just checking...what you did was enabled acpi in the kernel as well as emerged acpid?

(That's what I did to get me Inspiron 8100 to work)

I enable ACPI at the kernel, disable APM, and I get kernel oops. I don't have yet acpid emerged. I will try with that now, but the kernel oops was very early, during the booting, so I doubd that it has anytging to be with acpid.

Maybe something has to be configured in the bios? I should left APM to be able to use ACPI?

good question...I had APM enabled on my laptop as well as ACPI...perhaps they need each other?

no, which ever one gets loaded first stops the other from being loaded. apm and acpi are two totally different things for essentially the same purpose: to conserve power.

sorry about the tone, can't think of a better way to word it. :twisted:

oh...k. Thanks for clearing that up. :D

(ever notice how different people will read the same thing and see a different tone? I see just an explainatory tone which is not offensive, but just someone clearing something up.)

ok...here's my last stab at the problem...is acpi being compiled into the kernel? perhaps comiling it as a module would affect it in some way (or vice cersa)? I'm not at home where my laptop is currently so I can't check where mine is.

i use an inspiron 2650. the acpi information that i get from running 'cat' on the appropriate places proves that my bios is a big piece of crap. it says that no ac adapter is present, ever, even though it's obviously plugged in. it also says my battery is discharging even though i'm running off of the ac adapter. gotta love dell and their awesome bios implementations of the acpi standard. i heard it was bad, but had no idea. anyway, the point of this is to say that i compiled acpi into my kernel (not a module) and it boots up fine. perhaps passing an 'acpi=off' to the kernel at boot time and showing the output of dmesg (or if i'm being completely ignorant right now, you might have to look in your kernel messages log to figure out where the last boot was logged.. i can't remember at this point whether dmesg only shows the last boot or not) would help some, so we could try to pinpoint what's causing the oops.

please not that i'm not sure whether or not this is how you shut off acpi, but that's how you turn off apm at boot time if i remember correctly and i'd guess they'd be similar syntax.

hope you get it working!

I'm using ac-sources 2.4.21-rc1-ac2, it has many different things built-in that make the 8500 run smoother, including the newest ACPI kernel patches.

Also, check this site:
http://www.ee.surrey.ac.uk/Personal/G.Wilford/Inspiron8500/

Lots of great information and a few patches (some aren't necessary with ac-sources).

Good luck!
