Is this a Thunderbolt-attached GPU? AFAICS these errors are not caused by
missing bits in the device configuration but rather improper resource
allocation by the kernel. This is common with Thunderbolt, but Mika Westerb=
erg
has upstreamed a bunch of fixes for 4.15 and more are currently being
upstreamed:

Have you tried this on a 4.15 kernel or was it an older version? If the lat=
ter,
try on 4.15 again and see if the situation has improved.
