Po-Hsu Lin (cypressyew) wrote : clock test in monotonic_time will fail on Azure Standard_E4s_v3 / Standard_E64-16s

Among all of the Azure node, this test only failed on these two nodes:

Steps to reproduce:
 1. git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest-client-tests
 2. make -C autotest-client-tests/monotonic_time/src
 3. sudo autotest-client-tests/monotonic_time/src/time_test --duration 300 tsc

Results:
$ sudo autotest-client-tests/monotonic_time/src/time_test --duration 300 tsc

 Running 'make '
