Interrupt storm from XHCI

[raichoo]

Yes, I had some issues with my system freezing up over the weekend but
I rebuilt the kernel and world on Monday after upstream got merged. No
freeze
since then, I'm still not sure if the problem is still present (if it is I
could really
need some help to gather more info on the issue, I suspect it's KMS causing
trouble but that's basically just a guess, had no issue when running scfb).
Waking up after sleep sadly doesn't work as well but I didn't really expect
it to
(could also be worth researching).
Big benefit of using that branch is that I can adjust screen brightness ^^.
The
X1 display can be so bright that it hurts and scfb blasts at full
brightness and
cannot be adjusted.

Kind regards,
raichoo
