nouveau driver errors

1. Please describe the problem:

Kernels after kernel-5.8.16-300.fc33.x86_64 randomly result in display freezes, with the nouveau driver spewing errors in syslog.

2. What is the Version-Release number of the kernel:

Just reproduced it with kernel-5.9.10-200.fc33.x86_64

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

Probably kernel-5.8.18-300.fc33.x86_64. kernel-5.8.16-300.fc33.x86_64 seems to work for me, the next kernel I installed was kernel-5.8.18-300.fc33.x86_64, and issues started manifesting themselves.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Nothing specific. Freezes occur randomly

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:

kernel-5.9.10-200.fc33.x86_64 was just installed

6. Are you running any modules that not shipped with directly Fedora's kernel?:

No.

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

5.9.10 generated an avalanche of:

Going to attach additional logs, from various kernels of 5.18.16, with other errors.

The nouveau driver is controlling an old-ish

1:00.0 VGA compatible controller: NVIDIA Corporation GF108GLM [Quadro 1000M] (rev a1) (prog-if 00 [VGA controller])

chip, old enough to be fully supported by x.org's nouveau driver.

memtest86 completed a full testing cycle without any errors.
