--- Comment #6 from Eero Tamminen <eero.t.tamminen at intel.com> ---
On TGL, this happens in many additional tests, including 2 different Automotive
customer benchmarks.

In the SynMark benchmark, it happens in the following tests (when using last
evening drm-tip):
[  778.513869] Iteration 1/3: synmark2 OglCSCloth
[  778.849082] i915 0000:00:02.0: Resetting rcs0 for preemption time out
[  778.898748] Iteration 2/3: synmark2 OglCSCloth
[  779.097064] i915 0000:00:02.0: Resetting rcs0 for preemption time out
[  779.134308] Iteration 3/3: synmark2 OglCSCloth
[  779.329093] i915 0000:00:02.0: Resetting rcs0 for preemption time out
[  779.374631] Iteration 1/3: synmark2 OglCSDof

[ 1445.167415] Iteration 1/3: synmark2 OglPSPom
[ 1445.377107] i915 0000:00:02.0: Resetting rcs0 for preemption time out
[ 1470.346698] Iteration 2/3: synmark2 OglPSPom
[ 1470.553096] i915 0000:00:02.0: Resetting rcs0 for preemption time out
[ 1495.481206] Iteration 3/3: synmark2 OglPSPom
[ 1495.681099] i915 0000:00:02.0: Resetting rcs0 for preemption time out
...
[ 1876.058405] Iteration 3/3: synmark2 OglTerrainFlyTess
[ 1898.265122] i915 0000:00:02.0: Resetting rcs0 for preemption time out

[ 1927.116433] Iteration 2/3: synmark2 OglTerrainPanTess
[ 1952.646441] Iteration 3/3: synmark2 OglTerrainPanTess
[ 1969.121125] i915 0000:00:02.0: Resetting rcs0 for preemption time out
[ 1969.233106] i915 0000:00:02.0: Resetting rcs0 for preemption time out
[ 1969.345105] i915 0000:00:02.0: Resetting rcs0 for preemption time out
...
[ 2074.882611] Iteration 2/3: synmark2 OglVSDiffuse8
[ 2093.057110] i915 0000:00:02.0: Resetting rcs0 for preemption time out
[ 2093.169108] i915 0000:00:02.0: Resetting rcs0 for preemption time out
[ 2093.281111] i915 0000:00:02.0: Resetting rcs0 for preemption time out

(On ICL, Terrain tests run at >100FPS, CSCloth & VSDiffuse8 at >200FPS, so it
seems unlikely that draw calls in these test would be particularly slow on TGL
either, unless there's some other TGL specific bug in upstream Mesa / drm-tip
kernel.  SynMark above is Wayland version because X server crashes on TGL when
something tries to use it.)
