(gem_busy:1919) CRITICAL: Test assertion failure function one, file
gem_busy.c:270:
(gem_busy:1919) CRITICAL: Failed assertion: write[0] == ring
(gem_busy:1919) CRITICAL: error: 2 != 8194
Subtest extended-bsd1 failed.
Also, a lot of gem_busy and gem_exec subtests started skipping after the same
commit.
This issue is repeated on all IGT runs IGT_4292 - IGT_4297.
Note, for the runs I am referring to; IGT_4292 - IGT_4297, have both the same
IGT commit and kernel.
IGT-Version: 1.21-g305ebced (x86_64) (Linux: 4.16.0-rc2-CI-CI_DRM_3830+ x86_64)
The test look OK on CI_DRM_3830, this is the IGT commit that was integrated to
IGT_4292:

Iterate over physical engines
We current have a single for_each_engine() iterator which we use to
generate both a set of uABI engines and a set of physical engines.
Determining what uABI ring-id corresponds to an actual HW engine is
tricky, so pull that out to a library function and introduce
for_each_physical_engine() for cases where we want to issue requests
once on each HW ring (avoiding aliasing issues).</pre>
