With the commit above, I've started seeing boot warnings on a few

And same boards do not report problems on the next?

Looks like they do. I haven't checked it previously, but I see that we
have similar warnings on a few boards that KernelCI is testing -next on.


That's... horrendous.

I hope that we can get a proper fix with a bootloader update on these (now very
old) devices... Adding a Google engineer to the loop so that he can follow up
internally.

AFAIK that's unlikely going to happen given the resources needed from
the ODMs for a firmware re-qualification. Or we would have fixed the GIC
bug in ATF and had pseudo-NMI.

Some of the firmware code involved is 10 years old, so even the RK3399
Chromebooks, which no longer have support, could suffer from this as
well.

The alternative would be to hack-in a firmware node to mt8183-kukui.dtsi, but....
...ugh. That'd be indeed a hack for the sole purpose of fixing a bootloader that
is acting in a broken way, and I don't like that at all (...and I'm sure I'm not
alone!).


Then we should add it to the exception list. Let me take a look at this.

I sent a fix for this platform only. You did not paste links to other
failing platforms (and sorry but kernelci web interface was absolutely
unmanageable and unusable, so I am not going to even try to look for
them) so not sure who should be added to list of exceptions.


Are you aware of the new dashboard, or are you referring to the old one?

https://dashboard.kernelci.org/tree

P.S.: If you do have any feedback on how to make it better, please feel free to
give it out: the KCI team will surely be happy to read it.

Cheers,
Angelo
