This is an umbrella bug to help trace all the VIA ACPI/APIC bug people have been getting lately. Most of the failures hit USB and/or ethernet subsystems and occur with varying ACPI/LOCAL-APIC/IO-ACPI permutations on a wide range of motherboards [ simply put via acpi is broken right now only the actual symptoms differ ] People who hit this class of bug should open a new bug and mark it as blocker for this one so it can be closed once all repported via acpi problems are solved. It is very possible a single quirk will fix all via systems at once.
2.6.0-test4-bk2 : bug #10 still stuck, bug #71 almost solved
Bug #71 boot is solved except usb mouse is dog-slow Bug #10 has a working fix for one system. Please everyone test it on their systems
The working fix for Bug 10 does fix the IO-APIC problems here with my EPOX 8k5a3+. That's the first time I got net, usb and sound working in APIC mode. thanks!
Created attachment 805 [details] Output of VIA C3 which won't work unless acpi=off is specified on 2.6.0-test4+ the file "out" contains output of several of the suggested programs for ACPI output
Please create a bug per system and make them block bug 845. There are too many via systems suffering acpi/apic bugs to untangle them if they are all put in a single report (plus some of the failures may actually be caused by different bugs, so this way we can close a report each time a bug is squashed).
Created attachment 834 [details] VIA IRQ routing fix
Please try the attached patch. It should fix VIA IRQ routing problems.
The bugs this one depends on have all been resolved -- closing.
