Thanks for responding to my ticket! Sorry, I didn't have time to record down
all the relevant information until recently.

Anyway, the 60 Hz mode is missing completely. I attached the relevant logs to
the ticket.

I tried updating my clone of the kernel repo up to the commit at the end of
this post, but the issue persists. I will try the suggested patch and respond
as to whether or not it makes a difference for me.

Thanks again!
