BigSur and Monterey Apple Silicon Release bots are constantly exiting testing early with 500+ layout-test failures. You can see this on the following four queues: https://build.webkit.org/#/builders/Apple-Monterey-Release-AppleSilicon-WK2-Tests?numbuilds=50 https://build.webkit.org/#/builders/Apple-Monterey-Release-AppleSilicon-WK1-Tests?numbuilds=50 https://build.webkit.org/#/builders/Apple-BigSur-Release-AppleSilicon-WK2-Tests?numbuilds=50 https://build.webkit.org/#/builders/Apple-BigSur-Release-AppleSilicon-WK1-Tests?numbuilds=50 Here is a list of the test failures occurring: https://build.webkit.org/results/Apple-Monterey-Release-AppleSilicon-WK2-Tests/r288925%20(1332)/results.html They all appear to be tests that deal with layout and rendering, and they all have diffs that are just slightly off.

I was able to reproduce the failures using the following test at Monterey Release ToT: run-webkit-tests --no-build --no-show-results --no-new-test-results --clobber-old-results --exit-after-n-crashes-or-timeouts 50 --exit-after-n-failures 500 --release --debug-rwt-logging --no-retry-failures I was able to reproduce the failures at r288914, but not at r288913. So it appears that r288914 is what broke testing on Apple Silicon.
