Comment 1 for bug 2061930

Nvidia checked it over and saw it was a backport from the coresight stuff:

module_blacklist=coresight_etm4x

'fixes' it, but the modeset is still totally messed up on SMCI's grace hopper setup.

I dunno what other unintended consequences the pile of backports will have on the stability of the system, this will be a time-will-tell sorta thing.
