Hi, same for me. The screen does not freeze anymore and the boot succeeds. But now I have this kernel message during boot (for the second card): [ 24.382045] pci_pm_runtime_suspend(): nouveau_pmops_runtime_suspend+0x0/0xe0 [nouveau] returns -22 Do you want to have the complete dmesg log? I think this is a new bug. Your patch works for the previous one, so you can close it. Yours, Claas On 27.03.2014 11:54, Patrick Clara wrote: > I have tested this patch.
