I am generally following the kernel development, so I've already been through a
few 4.9-rcs and the 4.9 release by now.  I am currently testing the v4.10-rcs. 
None of these kernel versions have changed the "stuck on render ring" issue. 
It occures with a frequency of once or twice a week, usually as a result of
resizing an X client like an xterm.

The only noticable effect of upgrading the kernel was that the driver error
handling got significantly worse with v4.9-rcX and later.  It does not
successfully reset the GPU anymore.  Instead it tries again and again every
20th second.

Will look into this.  FYI, I am usually following Debian testing/sid wrt
userspace.

OK

> Let me know if you need more information on how to do any of this.

Hints are appreciated, but I guess I will figure it out by looking at how
Debian package these things.
