Hi, Josh.

I wasn't able to reproduce those errors using the ltp commit you have specified or the current master branch.

Can you provide more details about the environment you are running the tests on and the instance type as well?

We ran the LTP tests on a Standard_D14v2 and these 2 failures only happened on 4.15.0-1022, and they passed o n 4.15.0-1021, 1020, and 1018.

In the dmesg log here's the only thing interesting:

I tried to run the tests on a DS14_v2 and those tests are still passing. Is that the same instance type you are using? I couldn't find one named D14_v2.

Previously I was running the individual tests manually but even running the complete test suite, those test cases are still passing.

Is that a VM that you can provide me access to?

Looks good. LTP errors corrected by updating tests.
