HW test suites are having some flaky failures across unified and non-unified builds.

Some examples:
bvt-inline from reef for the reef-uni-release build:
https://uberchromegw.corp.google.com/i/chromeos/builders/reef-uni-release/builds/104

bvt-line from reef for reef-release build:
https://uberchromegw.corp.google.com/i/chromeos/builders/reef-release/builds/1333


From the log file, there aren't many clues (at least for me to decipher):
E.g. https://uberchromegw.corp.google.com/i/chromeos/builders/reef-uni-release/builds/104/steps/HWTest%20%5Bbvt-inline%5D%20%5Breef%5D/logs/stdio

For autotests perspective, all of the tests were aborted with little forensics around why they were aborted.
