And this one seems to be responsible. I believe -cip will need to do
something with it when it tries to merge 4.19.148... I hit it early
because 4.19.147-rt is not available, so I merged 4.19.148-rt with
4.19.147-cip.

Fix can be as simple as reverting
fb3a780e7a76cf8efb055f8322ec039923cee41f... I'm pretty sure noone
unloads modules in production.

Best regards,
