nvidia-graphics-drivers-390/390.154-0ubuntu1 ADT test failure with linux-raspi/5.19.0-1003.7

[Juerg Haefliger]

This is a scripted bug report about ADT failures while running nvidia-graphics-drivers-390 tests for linux-raspi/5.19.0-1003.7 on kinetic. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined.

Testing failed on:
    armhf: https://autopkgtest.ubuntu.com/results/autopkgtest-kinetic/kinetic/armhf/n/nvidia-graphics-drivers-390/20221013_013754_9419f@/log.gz

kernel doesn't provide function that the driver calls:

arm_heavy_mb() does not exist on the BCM2835 platform.

Ubuntu 22.10 (Kinetic Kudu) has reached end of life, so this bug will not be fixed for that specific release.
