The problem of entire shards failing is  Issue 628022 . I'll comment there on the whole-shard failures.

I don't know how to turn off the "without patch" steps in the chromium_trybot recipe. Pawel, can you offer advice? I think we want to change this bot's configuration so that it never does the retries without the patch.

You would want to touch https://cs.chromium.org/chromium/build/scripts/slave/recipe_modules/chromium_tests/api.py?q=chromium_tests/api&sq=package:chromium&l=678

It doesn't look like it's configurable at the moment. Pawel would know more about this. 

Pawel, could you help make this flag configurable somehow? Perhaps in a file like scripts/slave/recipe_modules/chromium_tests/chromium_gpu_fyi.py , and have the tryserver which mirrors that bot pick up the flag from there? I realize there's a problem with the generalized trybot mirroring wanting flags like this configured identically across all the mirrored bots. Would appreciate help thinking this through and implementing it. Thanks.
