[Kelsey Steele]

This is a scripted bug report about ADT failures while running linux tests for linux/5.4.0-75.84 on focal. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined.

Problem appears to be isolated to Focal. Seeing on Focal/linux and Focal/hwe-5.8. ppc64el only.

Failing with:
ftrace - Max stack tracer [FAIL]

Testing failed on:
    ppc64el: https://autopkgtest.ubuntu.com/results/autopkgtest-focal/focal/ppc64el/l/linux/20210603_094441_f3830@/log.gz
