Bug Description
[impact]
autopkgtest failure during test for linux pkg.
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.
