Screen goes black intermittently after installing F38

I have been running Fedora workstation on my Intel NUC home theatre PC without issue until version 37. I decided to install F38 Silverblue, but I am seeing the same issue if I boot from live image. The screen goes black intermittently for about 3 seconds.

[ 94.583848] i915 0000:00:02.0: [drm] ERROR CPU pipe A FIFO underrun

Intel Core i5-7260U
Intel Iris Plus Graphics 640 (Kaby Lake GT3e)(KBL GT30)
Kernel 6.2.11-300.fc38.x86_64

I am guessing that there is an incompatibility with this kernel. Can anyone suggest the best course of action?

Can you take a look at this bug, i5-10210U flickering display (built-in, HDMI and miniDP) and FIFO underrun while using USB and deep package C-states (#2077) · Issues · drm / intel · GitLab

I reviewed Joe’s suggestion.

I updated to latest firmware (from April 2023) and the issue still persists after I set:
intel_idle.max_cstate=<from 4 down to zero>

I also tried booting latest versions of other distros, and even with older 5.x kernels the same issue exists.
