The Mesa tests aren't needed to trigger the hang. Actually, the hang
doesn't even affect the tests running in the CI. However, during a job
execution we can see this warning multiple times, which ends up spamming
the log and can lead to confusion by non-kernel devs.
While inspecting the CI job, I was able to attest two things:
1. Indeed, the thread is created, but it never reaches
`wake_up_process()`, nor `vchiq_keepalive_thread_func()`.
2. Mesa's job environment doesn't load any media-related modules.
Therefore, no bcm2835-audio, no bcm2835-camera.

Yes, it is. It's also reproducible in a RPi 4 with the downstream
kernel. As RPi OS loads all those media-related modules, to easily
reproduce the error in RPi OS (without dealing with systemd and such),
you can just add the following modules to the modprobe blacklist:
blacklist snd_bcm2835
blacklist bcm2835_v4l2
# only for rpi4
blacklist bcm2835_codec
blacklist bcm2835_isp
blacklist bcm2835_mmal_vchiq
Reboot the device, wait a couple of minutes (2-3 minutes), and you will
get the warning in the dmesg output.

It's attached.
About the first point I mentioned in this e-mail, I'd like to come back
again to the idea that: the kthread is created, but it stays in
TASK_UNINTERRUPTIBLE forever, as we never call `wake_up_process()`. This
might be causing the kernel to report a hung task, which doesn't affect
the system, but ends up spamming the kernel log.
For example, we can see a similar situation described by commit
e5644be40797 ("usb: gadget: uvc: Fix unstarted kthread worker").
