Linux kernel 5.19.12 may damage laptops with Intel iGPUs.

It's recommended to avoid this kernel version with Intel iGPUs. I don't know how high the risk is here, but it's not something that is recommended to take a chance on. I happened to see this, and thought it was something people should be aware of.

"The Athenians, however, represent the unity of these opposites; in them, mind or spirit has emerged from the Theban subjectivity without losing itself in the Spartan objectivity of ethical life. With the Athenians, the rights of the State and of the individual found as perfect a union as was possible at all at the level of the Greek spirit." -- Hegel's philosophy of Mind

Thank god Debian is slow in updating their kernel in sid. And even if they got 5.19.12 into their repos, I'm on testing anyway, lol.

I'm lucky I do not have this problem since my laptops use Intel graphics chips.

Two of my laptops run Linux Mint 21 which use the 5.15 kernel and my third laptop runs MX Linux 21.2.1 which uses the 5.10 kernel.

Software damaging hardware? Always fascinating... Shouldn't the hardware protect itself from such issues?

Should, but it isn't the case all the time. Think about CPUs that allow a voltage and temperature that destroys them.

It's not always possible. Software can direct hardware to do things that are completely outside of design scope, and hardware design can't always account for all possible ways the hardware can be instructed, e.g. in loops/rapid repeats, etc. Sometimes it's as simple as just not having thought of a potential combination of factors that would need specific protection.

Two questions occur to me now:

Does this occur in linux-libre kernels and was it pushed out as an update for stable as a whole?

Hope its no to both of those... but who knows lol.

Actually one other question, which intel processors does this affect?

Or more accurately, which ones does this hurrt the most and which ones, the least?

I wonder...

Linux 5.19.13 was released to fix this problem:

Linux 6.0 was released two days earlier so I would assume they will remove the problematic Intel drivers from this release as well in a small point release:
