scheduler_test_wait_time failure on multiple architectures

[Matias Elo]

I'm observing occasional test failures on x86 (both i386 and amd64):

  Test: scheduler_test_wait_time ...FAILED
    1. scheduler.c:189  - odp_time_cmp(diff, upper_limit) <= 0

Comment 1 Dmitry Eremin-Solenikov 2018-09-04 07:23:55 UTC
Same environment (PPA builder) has generated following related test failure:

  Test: time_test_wait_ns ...Exceed upper limit: diff is 3022303549, upper_limit 2980000000
FAILED
    1. time.c:417  - CU_FAIL("Exceed upper limit\n")

Got same issue on arm64:

  Test: scheduler_test_wait_time ...FAILED
    1. scheduler.c:189  - odp_time_cmp(diff, upper_limit) <= 0
