Linux kernel 5.19.12 code could cause permanent damage to some laptop displays

For desktop Linux users, updating to a new Linux kernel typically carries relatively small, contained risks: wonky drivers, GRUB pain, maybe a full wipe and reinstall. For one subset of laptop owners on rolling release distributions, however, kernel version 5.19.12 could cause actual LCD screen damage.
"After looking at some logs we do end up with potentially bogus panel power sequencing delays, which may harm the LCD panel," wrote Intel engineer Ville Syrjala in a discussion on the issue. "I recommend immediate revert of this stuff, and new stable release ASAP. Plus a recommendation that no one using laptops with Intel GPUs run 5.19.12."
The conflict between Linux kernel 5.19.12 and Intel GPU drivers, captured by Michael Kan.
One day later, kernel 5.19.13 was released. But there's a distribution chain between kernel work and distribution desktops, and certain laptop owners were caught up in it.
