Comment # 9 on bug 1217344 from Rigo Wenning

I have also kernel failure with the latest tumbleweed kernel. When installing
it runs dracut for every single core. The system boots. But when I want to log
into KDE, it hangs forever. Console reports a failure to start powerdevil (for
whatever reason). So already the kernel install procedure seems fishy.

Again, Kernel 6.5.9 just works fine, boots, KDE runs fine.

I have a Dell latitude 7490. 

So even if it starts, I think kernel 6.6 has trouble interacting with KDE.
There seems to be something fundamentally wrong.

BTW, when installed for the first time, the system started and ran fine, even
after reboot. I haven't done any install since then. Now I have updated to the
latest tumbleweed 2023-12-02. That runs fine with kernel 6.5.9 but does not
work with Kernel 6.6.

I think this is a critical bug
