Title:
  glibc 2.27-3ubuntu1.3 ADT test failure with linux 4.15.0-119.120

Status in glibc package in Ubuntu:
  New

Bug description:
  Testing failed on:
      armhf: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-bionic/bionic/armhf/g/glibc/20200930_011321_6b874@/log.gz
      armhf+: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-bionic/bionic/armhf/g/glibc/20200929_030046_0d91d@/log.gz

  The failed test (tst-support_descriptors) appears to be new in the
  proposed version of glibc. Armhf seems to be the only arch failing. I
  did not see the test being mentioned in the runs for the current
  version of glibc (which fails for a different part).
