[gentoo-user] problems, with, 'hibernate, to, disk', two, nvidia, cards, installed

[meino.cramer@gmx.de]

Hi,

My gentoo box runs with linux kernel 3.1.6 (vanilla).
The hardware consists of an Asus Crosshair Formula IV
motherboard, a AMD Phenom II X6 1090T Processor and
two nviida cards:
    02:00.0 VGA compatible controller: nVidia Corporation GF110 [GeForce GTX 560 Ti] (rev a1)
    09:00.0 VGA compatible controller: nVidia Corporation GF108 [GeForce GT 430] (rev a1)

Previously I had installed the GT 430 card only.
With this card, hibernation to disk using sys-power/hibernate-script was no
problem.

Then I removed the GT 430 and uses a GTX 560 Ti for better performance
when rendering while utilzing the GPU.
With this card the same hibernation was no problem also.

Then on the Blender forum one came up with the idea to install both
cards. The GT 430 is used for desktop purposes then, the GTX 560 Ti
was used for rendering only.

With this setup hibernation is not possible anymore.

Whe starting the hibernation, the screen wents dark, but the PC does
not power off.

I had to push the power button finally and the reboot afterwards wents
through the normal process like after any normal shutdown...with the
exception, that the journals of the partitions had to be fixed.

/var/log/hibernate.log shows the following of the failed hibernation
and the boot afterwards:

I tried to blacklist the nvidia drivers (290.10), but the hibernation
couldn't unload this driver.

How can I get back the hibernation functionality?

Thank you very much in advance for any help !

Best regards,
