In the Linux Kernel 6.12, according to the Phoronix resource, there will be a function for displaying a QR code during critical kernel panics. The idea is to provide users with as much detailed information as possible about the causes of the “screen of death” and possible solutions to the problem.

A similar tool is integrated directly into the Linux 6.12 kernel, so even if the operating system completely crashes, the user will still see a QR code describing the problem. A QR code is a fairly powerful and important tool for finding out the cause of a critical failure, especially considering that the conclusion about the causes of problems is usually cut off. Support for the new function is implemented as a Rust module. The operation of the tool is controlled by the DRM_PANIC_SCREEN_QR_CODE parameter.
It should be noted that Microsoft added a QR code to the Windows Blue Screen of Death in 2016. But when scanning it, the user only gets to a general support page without receiving any additional details. Instead, you are prompted to restart your computer, open the Get Help app, and then enter “Troubleshoot BSOD error.” However, this approach is useless if the “screen of death” appears every time you turn on the PC.
