Random crashes easily reproducible with make -j5 - intel i915 -kernel 2.6.36 on intel/nvidia hybrid graphics machine

[Giacomo]

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.

Switching back to kernel 2.6.35 _seems_ to solve the problem (at least
I have not been able to reproduce
the behaviour in the last 4 days...)

Are there any know issues / bug reports for the kernel 2.6.36
concerning this problem?

Thanks.

I attach my kernel configuration
