Subject: [bugreport] 3.2_rc2 and several previous versions: Intel 945GC blanks
screen after trying to initialize KMS. Kernel trace is printed and X.org
server does not find screen.
Hi,
I don't know if I am directing this bug report to the right person but
here it goes.
I have just tried kernel 3.2_rc2 to find out if this problem still
holds, and it does.
I have a foxconn motherboard with an Atom 330 + 945GC onboard graphics.
I started to use the recent i915 driver with KMS, got a blank screen,
X.org finds no screen
when using the latest intel drivers and so on. However I noticed the
following during some experimentation:
1. If I add the kernel boot option: 'acpi=off', everything works
(except acpi obviously)
2. If I use 'acpi=ht' (I know it has been removed from the recent
kernels, but I reverted the patch in my local git clone for this
experiment)
everything works.
3. If I use 'pci=noacpi', everything works
4. If I use 'acpi=noirq', I have the problem
5. If I use 'pnpacpi=off', or 'noapic' or 'nolapic', I also have the problem.
So for know, I stick with the 'pci=noacpi' to have a working KMS and X.org.
Also, an other atom 330 and i945 chipset based nettop, which has an
original Intel board instead of the foxconn, works flawless.
Below I have included the kernel trace that is dumped due to the bug.
Kind regards,
Xander Hover
