21:22 ickle : <3> [385.741372] Switching between 241 contexts timed out 21:22 ickle : ... 21:22 ickle : <7> [385.848580] i915_gem_set_wedged \x09Execlist CSB read 2, write 5 [mmio:5], tasklet queued? yes (enabled) 21:22 ickle : ksoftirqd strikes again 21:23 ickle : no, that maybe a little simplistic 21:23 ickle : it executed 1a06 and 1a07 whilst dumping the state 21:24 ickle : so maybe it just accumulated a lot of slowness
Do we need more occurrences of this to investigate? So far there has been one.
This one has the hallmark of being an uncommon sw issue. I'm still betting on ksoftirqd being at the heart of it, proof left to the imagination.
Still no other occurrences. I'm going setting it to high priority.
https://intel-gfx-ci.01.org/tree/drm-tip/Patchwork_10950/fi-cfl-8109u/igt@i915_selftest@live_contexts.html Same again, running very slowly but progress is still being made. Still taking over 2s for a 100 context switches is bogus.
Occurred several times in a day, then never again for almost two months. Closing.
