Kernel panic - not syncing: Attempted to kill the idle task!
Trying Fedora 44 beta, I get a different error message:
Kernel panic - not syncing: No working init found.
I don't have that problem when not using NVMM, although the VM is
obviously horribly slow. I don't have that problem either with
older Linux kernels (6.12 is fine).
When not using NVMM with Fedora 44 beta, it's different but no
better:
Failed to start up manager.
systemd[1]: Freezing execution.
It happened to me some time ago with newest archlinux, I boot from the cd, choose edit boot command, add noapic, it boots ok I do not remember if it was the solution... try
