This is for sure not a duplicate of bug 105556, since that bug is softdog incomplete and this is piglit timeout due to change in the CI system configuration. Before the configuration change the softdog did not hit the pinpointed machines on the test.

    igt/gem_ctx_switch: Measure qlen for timing loops
    
    Some platforms may execute the heavy workload very slowly, such that
    using a batch of 1024 takes tens of seconds and immediately overrunning
    the 5s timeout on a pass. Added up over a few dozen passes, this turns a
    120 second test into 10 minutes. Counter this by doing a warmup loop to
    estimate the appropriate queue len for timing.

Will take some time to get results since this is only reproduced when BAT machines run the shards testlist.
