4.19.1-rt3 kernel bug (BUG:Scheduling while atomic) was created by bevins
My machine is locking up and found it to be caused by a bug in the 4.19.1 RT3 kernel.
I installed the linuxmint iso. Is there another RT kernel I can use with Linuxmint?

Are all the iso's guys are creating using this kernel?

Yes, it had the best latency from all the ones i tested. I dropped from 5.4 to 4.9 ! :)
Download that, install using gdebi, reboot and hold down shift key, choose that kernel in advanced options, test if it works ok.
If not just leave it there, GRUB will still load 4.19 by default. So in case it works you have to make it the default in GRUB.

Is it worth trying to find the headers and recompile this older kernel with support for the 8192eu module?

Any other rt kernels around that would support the 8192eu module?

packages.debian.org/bullseye/amd64/linux...-3-rt-amd64/download
That is the newest RT kernel, so should have drivers for your wifi.
