casper/1.470.2 ADT test failure with linux-hwe-5.19/5.19.0-40.41~22.04.1

[Kleber Sacilotto de Souza]

This is a scripted bug report about ADT failures while running casper tests for linux-hwe-5.19/5.19.0-40.41~22.04.1 on jammy. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined.

Testing failed on:
    amd64: https://autopkgtest.ubuntu.com/results/autopkgtest-jammy/jammy/amd64/c/casper/20230403_091405_2f860@/log.gz

This test seems to have regressed with hwe-5.19 in Jammy when casper got updated from version 1.470.1 to 1.470.2.

Latest debug messages from the test log file:
