From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030701 Epiphany/0.9.3 Description of problem: This is a popular model laptop and as such should be targeted for full support asap. Of course this is not including the winmodem. But having to patch my dsdt to get acpi working is a bummer. See this link for an example of the trials necessary to get Linux running... although once it's running it runs great! http://ltswww.epfl.ch/~dsanta/resources/dell-i8500-linux Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Install Red Hat Linux (any) 2.Work on your Laptop after strugging to configure X due to the uncommon screen resolution. 3.Watch your laptop overheat and battery power not hold up due to improper power management Additional info:
Have you tried the latest kernel from rawhide ? It has updated ACPI, and the Speedstep-ich cpufreq module.
Yes, I think it is due to Dell's BIOS being Blacklisted... the DSDT needs to be patched in order to get ACPI support that works... I'm just suggesting this be included in any upcoming releases.
why is it being blacklisted ? If its because its pre-2000, you can override with acpi=force.
Dell Inspiron 8500 Last Modified 2003-07-09 14:46 by Adrian Dewhurst S4 Bios no Original no SMP no Bios Revision A03 APIC Table no Board Revision Boot Table no DSDT Vendor S2 Latency 0 DSDT Product S3 Latency 0 DSDT Revision 0 Dutywidth 0 Interpreter Fix Dell's code incorrectly assumes that all arguments are passed by reference, when they are actually passed by value. There are two methods affected by this, so they have been modified to explicitly pass references. It has been removed from the blacklist apparently but the bios is buggy... a patch is still needed to get it to work correctly...

No updated BIOS available ?
Yeah, Kernel 2.4.22 seems to be running smoothly with default acpi and patched cpufreq with an updated bios. Still no support for volume keys other than acme (a good userland solution but only with GNOME and XFce4 with work)... also, i8kutils required for fan control...
Kernel 2.4.22 vanilla sources... not red hat version but they should be the same minus red hat's tweaks.
