Shibi:
I can't answer your question, and even don't know what it means, but I
have a Dell Vostro 3500 with an Intel card and when using the battery I
also get this error message when the system comes back from suspending
... just to say that you are not alone :)
Germán.
finally new update to kernel-3.1.5 blows everything up. when i boot
with new kernel it claims about radeon dri and tainting plymouth, it
can run xorg (cursor appears) but it cann't load GDM at all.
disabling kms with radeon.modeset=0 in grub can solve the problem but
makes vgaswitheroo disapear, that is a great requirement for me
because of heating, battery drain and fan malfunction.
