More strange behaviour with new kernel.
Although lightdm allows me to login, akonadi cannot start properly which prevents me using kmail & other PIM components.
booting into previous kernel -348  all issues are resolved.

Same issue in kernel 4.18.0-365.el8.x86_64

Comment 4 Troy Dawson 2022-03-17 20:06:37 UTC

Just incase this isn't a kernel bug, I've noticed something I can't pin my finger on.

On the bad kernels, it takes a minute and a half to shut down.
If you do a <Ctrl>-F12 you will see
  A stop job is running for Simple Desktop Display Manager (30s / 1min 30s)
Which will count up to 1min 30s.

So, sddm is clearly stuck on something, both starting up, and shutting down.
But I can't figure out what.

Comment 5 George 2022-06-09 08:40:25 UTC

Resolved with kernel update
