Disable ACPI, or enable IO_APIC (and hope it's there). I'm betting it doesn't have an IO-APIC (its a laptop, no SMP, etc) .. any way to tell if the APIC is working/enabled? (For that matter, all google could tell me about was the IO-APIC, which is handy to know but not particularly helpful here.) > > (Full dmesg attached, for those who are curious - the unknown-scancode > > is for the various laptop buttons - bright/dim, vol, media, battery, > > etc. Except for the volume buttons the only ones that work are the ones > > that directly hit the hardware, ala bright/dim.) > > > > Also, for others with an I8500 who might read the dmesg log, don't get > > dmidecode data would be nice, for the whitelist rules. Attached (I pulled out the service tag and express service code, both of which are local to the individual device.) Also, not sure what (if anything) would be different with the A01 bios; their changelog seems to focus mostly on fixing a sound bug (which, unfortunately, I didn't have until -after- the fix... sigh.) Their changelog is online ( support.dell.com 'small business' -> 'Inspiron 8500' -> 'FlashBIOS updates') but there's not much to it. -- Disconnect --=-wyQ/aEHpEgfBnmFrCp00 Content-Disposition: inline; filename=dmidecode.txt Content-Type: text/plain; name=dmidecode.txt; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit # dmidecode 1.8 SYSID present.
