Kernel issue with Intel video

Yikes! Has a Linux kernel ever damaged people's hardware before? … he-display

Intel Linux laptop users on Linux 5.19.12 have begun reporting "white flashing" display issues with one user describing it as "[the] laptop display starts to blink like lights in a 90's rave party." Intel Linux kernel engineer Ville Syrjal posted this week on the kernel mailing list: "After looking at some logs we do end up with potentially bogus panel power sequencing delays, which may harm the LCD panel."

Re: Kernel issue with Intel video

Why are you posting about ancient kernel versions?

$ cat /proc/version                                                            
Linux version 6.0.0-zen1-1-zen (linux-zen@archlinux) (gcc (GCC) 12.2.0, GNU ld (GNU Binutils) 2.39.0) #1 ZEN SMP PREEMPT_DYNAMIC Tue, 04 Oct 2022 19:16:30 +0000

Poor old sid is still on 5.19.11, lagging behind has it advantages sometimes...

EDIT: looks like this might be a consequence of Intel's support for their new Arc graphics cards. Regressions are a pain but at least Intel are finally putting some effort into their graphics stack. Disclaimer: this is just a guess.
