a/tar-1.35-x86_64-1.txz:  Upgraded.
x/mesa-23.2.0_rc1-x86_64-1.txz:  Upgraded.
  OK, usually I won't use rc versions even in -current, but in this case I'm
  going to. Some time ago my desktop machine with RS880 / Radeon HD 4290
  graphics on the motherboard began acting up with the screen going black
  for a few seconds before returning. This after an hour or so of uptime,
  usually, then becoming more frequent with more uptime. Eventually I'd lose
  mouse and/or keyboard too, and have to reboot. Here's a couple of errors
  from dmesg:
    [ 9942.677675] [drm:r600_ib_test [radeon]] *ERROR* radeon: fence wait
                   timed out.
    [ 9942.677741] [drm:radeon_ib_ring_tests [radeon]] *ERROR* radeon: failed
                   testing IB on GFX ring (-110).
  I also noticed that the backtrace started with ttm_bo_release, and seeing
  this in recent kernel patches had been chalking this up to a kernel bug.
  I *still* think it could be, and there are a bunch of kernel patches coming
  soon to -stable from Alex Deucher that could address the underlying causes
  (not for 6.1.39 though, unfortunately). Anyway, I'd recently figured out
  that reverting Mesa sufficiently made the issue go away. And now it seems
  this 23.2.0 release candidate also fixes the issue.
  Yes, I could go search for the commits to cherry-pick, but we'll be moving
  to mesa-23.2.0 when it's released, so we might as well start testing now.
