            Bug ID: 99482
           Summary: nouveau driver returns -16 trying to hibernate
           Product: xorg
           Version: 7.7 (2012.06)
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: brian-SquOHqY54CVWr29BmMi2cA@public.gmane.org

I am running Fedora 25 with kernel 4.8.15-300.fc25.x86_64.  I don't actually
actively use the nouveau driver as my machine has an Intel/Nvidia hybrid so I
use the Intel driver for X.  But even when I do that, the nouveau driver gets
loaded (with 2 references) unless I blacklist it.

So given the above, when I try to hibernate it typically works once but a
second attempt to hibernate (after having been woken up of course) will fail
and the kernel reports:

As you can see, the fatal part is the:

Jan 20 17:42:15 laptop kernel: pci_pm_freeze(): nouveau_pmops_freeze+0x0/0x20
[nouveau] returns -16
Jan 20 17:42:15 laptop kernel: dpm_run_callback(): pci_pm_freeze+0x0/0xf0
returns -16
Jan 20 17:42:15 laptop kernel: PM: Device 0000:01:00.0 failed to freeze async:
error -16

If I do blacklist the nouveau driver completely so that it does not get loaded
into the kernel even, I can hibernate and resume over and over again with no
problem.
