Bug Description

I had numerous kernel panics after upgrading to the latest kernel. Reverting to the previous Release 4.15.0-147 fixes the problem. I first noticed this when my desktop was "stuck". I switched to the console to run htop, to see if anything was blocking. And this seemed to consistently trigger the oops.

Hello, I've got a few guesses:

- incompatibility with vbox, in which case oracle would probably need to be involved
- ran out of memory, I see some AppArmor ALLOWED entries with //null- profiles involved, depending upon how often sssd does those operations it's possible this could consume unswappable kernel memory. It would be best to extend your sssd profile and put that back into enforce mode.

Thadeu, Ben, any other thoughts? Is there a reason to keep this private?

Thanks

This is not my private machine, so I can not change anything related to sssd.
