    <thetext>Hello,

This seems to be a timeout unrelated to a specific test:

---
WARNING: core-image-ptest-lttng-tools-1.0-r0 do_testimage: Couldn&apos;t login into serial console as root using blank password
WARNING: core-image-ptest-lttng-tools-1.0-r0 do_testimage: The output:


qemux86-64 login: &lt;&lt;&lt; run_serial(): command timed out after 120 seconds without output &gt;&gt;&gt;

qemux86-64-musl-ptest debian11-vk-1

I&apos;m opening this one just in case, but there are no actual timeouts or failures in lttng-tools itself:

    <thetext>It&apos;s affecting util-linux this time, but very likely the same issue:
