Public bug reported:
Issue found with K-5.19.0-28-generic on P9 node baltar
This should not be considered as a regression since
ubuntu_kernel_selftests will be blocked by the net test crash before
this powerpc tests can be started. This was found by manually running
the test.
Test build failed with:
gcc -std=gnu99 -O2 -Wall -Werror -DGIT_VERSION='"unknown"'
