inteldrm - crash on boot

David Hill-3
I have a Purism Librem15 laptop that always panics on boot.

Traced back to this commit:
https://marc.info/?l=openbsd-cvs&m=155523690813457&w=2 

Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to
linux 4.19.34.


I have typed out the debug below.  


NMI ... going to debugger

panic: kernel diagnostic assertion "_kernel_lock_held()" failed: file "/usr/src/sys/dev/pci/drm/drm_linux.c", line 496
