re: kern/58710: amdgpu kernel bug -- modesetting driver GL Rendering failure

is there a chance you can try -current on this system?  for me it
was working mostly good with an RX 550, but i don't recall trying
netbsd-10 branch recently.  i'll try to find time to do that, but
i can't promise anything for a week or more.

i wonder if you, like me on some systems, are missing the render
nodes in /dev/dri that are created i modern systems, but not there
for older ones that have been upgraded.  eg, i just created this
on one system it was missing on:

the-blessing /dev# l dri
total 0
crw-rw----  1 root  wheel  180, 0 Jul 24 20:47 card0
the-blessing /dev# sh MAKEDEV drm0
the-blessing /dev# l dri
total 0
crw-rw----  1 root  wheel  180,   0 Jul 24 20:47 card0
crw-rw----  1 root  wheel  180, 128 Sep 30 13:05 renderD128

i don't *think* this is relevant, so if it doesn't help are you
capable of patching Mesa to expand the errors and determine where
exactly the shader creation is failing?  if so, please add some
diagnostic to si_create_shader_variant() to track down which of
the various paths that return false was taken?

thanks.
