Title:
clock test in monotonic_time will fail on Azure Instances
Status in ubuntu-kernel-tests:
Confirmed
Status in linux-azure package in Ubuntu:
Confirmed
Bug description:
Among all of the Azure node, this test only failed on these two nodes:
Seen on the following instances:
Basic_A2
Standard_D2_v3
Standard_D2s_v3
Standard_E4s_v3
Standard_E64-16s
Standard_F2s_v2
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 '
