I didn't know that newer firmware was available, what I had dates
from when I got this box.  I've just downloaded
linux-firmware-20211027.tar.gz, last time I looked at firmware I
needed to get the individual files.  So, I didn't have that
picasso_ta and I do now.  But it still doesn't load - the mention of
a runtime database makes me think it might be for wifi ?  If so,
this machine is wired only.

I forgot to do that until I came to reply.  I've attached the kernel
log from running with only the updated firmware as sys.log.gz

Turning off the iommu was pretty disastrous, screen went blank
before I could login.  Turns out it had oopsed (from 2.316893
seconds in the attached sys.log.iommu_off.gz).

Thanks.
