[Bug 1809757] [NEW] odd issue after upgrade of kernel

Public bug reported:

after upgrading to 4.18.0-13, audio, multiple monitor, and some
keyboards stopped working (dmesg/lsusb would always detect the keyboard,
but only a subset of them could actually be used.

also tried installing many previous versions of the kernel from
4.15.0-20 to what i am on now, but none of them work either.
