The NAP was always a crock of shit. There is no real rhyme or reason to it. Just a Libertarian’s way of saying “You started it!” every time they get into a physical altercation.
This has happened to me only once on Linux. I still tell stories about it.
It was a CD burning program stuck in uninterruptible sleep! Trapped in a system call into the kernel that can never be interrupted by a signal, it was truly unkillable. The SIGKILLs simply piled up never to be delivered.
THIS is your big “You won’t believe what happened to me…” story???

When I was 14, I took the power cord for the original PS1 and shaved the rubber off the end until metal prongs were sticking out. Then I noticed if the outlet end was plugged in, and you touched the metal prongs on the other end, you couldn’t drop it. It would electricute you, but it would also stick to your skin for 5-10 seconds as it electricuted you.
So being a 14 year old male, I did the only logical thing. I put it on my penis.
In this case it was a driver holding that thread captive and making an assumption about the hardware eventually responding to a request which never completes.
So yes indeed it was the kernel, and ideally the driver could be written better, but that’s probably easier said than done when the hardware can do weird things.
This was a long time ago, so for all I know the issue has been long corrected.
A while ago I kept a shortcut in the taskbar that ran a batch file that killed any unresponsive task, worked even on those tasks that Task Manager can’t seem to close. As long as explorer was still running and I could alt tab and press that button it worked 100% of the time
It was something like this. It would just kill all tasks that haven’t responded in X amount of time. Obviously this is not a great solution as it can cause data loss and you could accidentally close more than just the program you intend to close, but sometimes you have little choice.
