[REGRESSION] GM20B pmu timeout

Thx for the report. Hmmm. No reply so far. :-/

Diogo, maybe report this here as well:
https://gitlab.freedesktop.org/drm/nouveau/-/issues/

Afterwards drop a link to the ticket here. Reporting nouveau issues via
email should work, but maybe you have more luck there.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker'
hat)
