Description Giacomo 2010-12-09 13:26:17 UTC 
Hi. I have experimented random crashes (system hangs - reboot necessary) on my
asus U30J i915 / nouveau.

At the moment, I am still unable to switch to nvidia graphics.
So I am using intel i915 with xorg intel drivers.


x11-drivers/xf86-video-intel 2.13.0

x11-base/xorg-server 1.9.2.902

kernel 2.6.36

I can reproduce it quite easily by

- booting the machine
- building something with make -j5

after some seconds or minutes I find the machine is hung.

Sometimes the screen is black (maybe because meanwhile power management has turned the screen off), sometimes the screen is simply
freezed.

Must force shutdown. No traces in the logs.

I attach my kernel configuration

Below the output of lsmod:

Does it make any difference if the nouveau module is never loaded? Does it make any difference if i915 is never loaded?

Duping to the linked regression tracker.

The nouveau module wasn't even compiled when the crash used to happen.
Another detail: kms was built as a module and the machine booted with
kernel parameter i915 modeset=1.

In the kernel 2.6.35 to which I switched back (and where I still haven't
run into this issue so far) kms for intel is built in.

I did not try to switch to nvidia drivers yet.
To do that I would have to blacklist i915 and install nvidia proprietary
drivers I think... so far vga switcheroo does not work for me and nvidia 
proprietary drivers hang the machine if i915 is loaded.
