Nouveau - Feb 2021 - drm/nouneau: 5.11 cycle regression bisected to 461619f5c324 "drm/nouveau: switch to new allocator"

Please try to add a "return NULL" at the beginning of
ttm_pool_type_take().

That should effectively disable using the pool.

Thanks for testing,
Christian.

That did away with the yield looping, but it doesn't take long for the
display to freeze.  I ssh'd in from lappy, but there was nada in dmesg.
