More APIC woes

I noticed yesterday that the output from /proc/interrupts listed usb and network on the same irq (see 11).

I had hopes of having usb work now that I had switched everything to XT-PIC (noapic). Of course, that would be too easy. I clearly don't understand the full ramifications of turning APIC off, but without it, there is no USB. I can only assume it is receiving no interrupts. At least my network card still works.

TODO

This list only contains the current issues I'm working on. For a complete list of issues and fixes, please see the functionality summary.

• APIC works, but I've got about 20 IRQs (which isn't right) and it only boots 1/3 of the time with the current fix.


• Sound doesn't automatically transfer to headphones, so I have to mute the speakers myself.
  
  
• Bluetooth doesn't work.


• Wireless doesn't work.


• Learn how to manage the Synaptics options (and turn off all the touch pad back/forward/scroll/reload stuff)


• Flash doesn't work because it's a 64-bit system
  

X fails to start due to edge-triggered interrupts

I rebooted my laptop this morning to find that X would no longer start. Shame on me for upgrading. The error message I received was

(EE) NVIDIA(0): The interrupt for NVIDIA graphics device PCI:x:x:x
(EE) NVIDIA(0):      appears to be edge-triggered. Please see the COMMON
(EE) NVIDIA(0):      PROBLEMS section in the README for additional information.

The last time I heard anything about edge-triggered anything was my first year of college, so all I got out of this message was "Something is misconfigured." I google the error and find the "Common Problems" section. There are several version of this file running around, each with different amounts of information. This is the best one I found: http://download.nvidia.com/XFree86/Linux-x86/1.0-9629/README/chapter-05.html


I checked /proc/interrupts and sure enough, everything was set to edge-triggered. This could explain several of my hardware issues. The quickest way to getting a working laptop seems to be throwing "noapic" in as a kernel argument, so the pertinent entry in my grub.conf now looks like:

title Gentoo64
root (hd0,1)
kernel /2.6.17-r8.usb root=/dev/sda5 noapic
#initrd /initrd.img

I'm not too happy with this solution, but at least I can use my computer.

dv6000z details

For those of you who are playing from home, here are the specifics of my laptop. If there's a detail you think is pertinent that isn't here, post a comment about it and I'll try to address it. This is what was in the email from HP when I ordered it:

- Genuine Windows XP Home Edition
- AMD Turion(TM) 64 X2 Mobile TL-56 (1.80GHz/512KB)
- FREE Upgrade to 15.4" WXGA BrightView Widescreen!
- 256MB NVIDIA(R) GeForce(R) Go 7200
- HP IMPRINT Finish + Microphone

- FREE Upgrade: 8X DVD+/-R/RW w/Double Layer Support
- 802.11a/b/g WLAN & Bluetooth

- Microsoft(R) Works/Money

I'm sure glad I got that copy of Works. Where would I be without it? Anyway, this is what lspci says

dv6000z + linux = :(

A little while ago I bought the HP dv6000z. It had all the hardware I was looking for at a decent price. The problem is that it doesn't really work very well with linux. I was hoping that if I waited a little while, someone else would put together a HOWTO so I could just ride the open source coat tails. No game on that one, so I'm starting this blog to document my quest to get everything working.
