Hi Mathieu,

I reviewed the build logs and observed that the generated rootfs does 
not contain the lib/modules directory,
which should normally be created when kernel modules are installed into 
the image.
Unfortunately, I was not able to find sufficient information in the logs 
to explain why this is happening.

I attempted to reproduce the issue multiple times locally on an ARM host 
and x86_64 host, but i am not able to reproduce the failure.

So far this intermittent failure seen only on arm host. So, we are 
planning to run a few more tests on ab with some debug info added to the 
test case.
If the issue still cannot be reproduced, we will temporarily skip this 
test on arm64 for this release.

Will keep you posted by beginning of next week.

Thanks,
Harish
