Hi Jani and everyone,

The patch works. (Applied on top of 6.16.0-rc2-1.1-mainline, built by 
Christian @gromit who helped again.)

The patch (or the new kernel) also have a side effect of xrandr allowing 
a completely new refresh rate, ~144Hz. This new refresh also seems to 
work (I cannot easily disambiguate 144 versus 120, but I can tell it's 
not 60Hz). So as far as my hardware is concerned, this patch leaves the 
whole system working in all scenarios that I've tested.

Thanks!


Kind regards,
Vas
