We should be using PFP as much as possible.  Does the attached
patch help?
Unfortunately not.
Maybe add a readback of the VM base addr pointer to make sure that the
write has really reached the SBRM?
I'm not sure what exactly you're thinking of, but I'm happy to test any
patches you guys come up with. :)

Maybe some variant of this patch?
Ignore that one.  typo.  Try this one instead.
Thanks, but still no luck.
I'm out of ideas at the moment.  I'll apply your patch unless
Christian can think of anything else.

Unfortunately not, so apply the patch for now.

Christian.
