Hi!

It seems

commit fb3a780e7a76cf8efb055f8322ec039923cee41f

    ravb: Fixed to be able to unload modules

causes problems in at least -cip-rt kernels. (I'd have to verify it is
present in -cip and plain -stable). Symptoms are like this:

Reverting the above patch fixes the problems.

If you have any ideas what could be going on there, let me know.
