This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

ADJ_OFFSET during test causes skew, and test to fail. [test case] this only happens intermittently, but frequently on the autopkgtests. when it happens it looks like: 20:46:54 DEBUG| [stdout] WARNING: ADJ_OFFSET in progress, this will cause inaccurate results 20:48:54 DEBUG| [stdout] Estimating clock drift: 16.881(est) 27.184(act) [FAILED] when it happens with a patched kernel it looks like: 01:04:35 DEBUG| [stdout] WARNING: ADJ_OFFSET in progress, this will cause inaccurate results 01:06:35 DEBUG| [stdout] Estimating clock drift: 14.52(est) 13.641(act) [OK] [regression potential] since this skips the test in question, it might miss an actual regression that the test should have caught; however, since ADJ_OFFSET is not always in progress during the test, if a real regression happens for this test, then it should correctly fail for test runs which have no concurrent ADJ_OFFSET and thus don't skip the test.
