I've got a t210 nano a02 that essentially hasn't been able to load
nouveau since I've started my Android Common Kernel effort over two
years ago. I think it came up like twice when I accidentally left it
boot looping for days and forgot about it, but never when I wanted it
to.

With this series, nouveau loaded properly 3/3 boots. I'll keep this in
my 6.18 kernel fork and see if any of my t210 devices hit the probe
hang and will report back if I find a case this doesn't solve. I will
also point other people I know with units affected by the issue to
this series.
