Subject: PROBLEM: PCI setup hangs on Asus Notebook (nolapic helps)

Hello,

my Asus M2N Notebook hangs doing the following on 2.6.22-rc3 (from Ubuntu
Gutsy Gibbon Tribe-1):

Setting up standard PCI resources

The non-scrollable output on the full screen can be found here:
http://planck.djpig.de/~mcornils/pci-hang.jpg

Booting with nolapic helps, but makes the SATAized IDE controller buggy
(spontaneous timeouts occuring, which do not happen on OpenBSD or Windows XP
(shiver)).

I'm using the latest BIOS (A208). Now I know it's buggy as hell and I've
already complained to Asus, but to no avail.

There have been other reports of the problem on Asus notebooks. I've collected
some links:

https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/83290
http://bugzilla.kernel.org/show_bug.cgi?id=7906 (maybe related)
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/8012 (maybe
related)
http://lists.debian.org/debian-user-german/2006/12/msg01017.html (german)

I'm willing to provide any needed information (like DSDT table, system
info, ...) and try out almost anything (I do not have a serial console handy
though - the system does not have serial).

Yours,
-Malte

Are any of these problems new behaviour, or has it always done this?

If there _is_ new behaviour here, are you able to identify which earlier
kernel versions did not exhibit it?

The patch causing that behaviour went in between 2.6.18 and 2.6.19rc-1. I have
some 100 patches to go bisecting the bug, but it's slow work due to
difficulties in getting physical access to the machine for extended periods
of time.

I'll be sure to let you know when I have the exact commit. That may be at any
time from tomorrow to beginning of July, I'm not sure yet what my free time
allows.

Yours,
-Malte

OK, thanks. There's no rush but please do persist...
