They should make it black instead.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The kernel art department really failed us here. Instead of a blue screen of death we could've had, I don't know, literally any other colour. I'd have gone with the Puce Screen of Panic.

Of all the things to take from windows, this is one of the better ones. Especially if it gets more info in the future. For less tech-literate users, a screen like this is a lot better than a hard to read dump to a terminal.

It's beautiful. I assume they'll dump the kernel oops log if there's any.
What's DRM in this context? Surely linux kernel doesn't do digital rights management?
Direct Rendering Manager. Part of Linux kernel to communicate with GPUs.

It is not informative yet, but I like that it's blue. It's a quite recognizable color. Windows made it recognizable by having a lot of BSODs. People are asking why it couldn't be just black, but with non-black BSOD one can recognize it instantly without reading the text.
Just for reference, a few years back, (ex-Microsoft) David Plummer had this historical dive into the (MIPS) origin of the blue color, and how Windows is not blue anymore: https://youtu.be/KgqJJECQQH0?t=780
Oh, thanks! I don't know much about the current state of Windows.

This is the best summary I could come up with:
After being talked about for years of DRM panic handling and coming with a "Blue Screen of Death" solution for DRM/KMS drivers, Linux 6.10 is introducing a new DRM panic handler infrastructure for being able to display a message when a panic occurs.
With Linux 6.10 the initial DRM Panic code has landed as well as wiring up the DRM/KMS driver support for the SimpleDRM, MGAG200, IMX, and AST drivers.
For those curious what DRM Panic can look like in action, Red Hat engineer Javier Martinez Canillas shared a photo of the DRM Panic "Blue Screen of Death" in action.
A BeaglePlay single board computer was used and Javier posted to Mastodon of an example implementation:
It could be extended in the future with some operating systems having looked at QR codes for kernel error messages and other efforts for presenting more technical information while still being user-friendly.
On Linux 6.10+ with platforms having the DRM Panic driver support, this "Blue Screen of Death" functionality can be tested via a route such as echo c > /proc/sysrq-trigger.
