So I removed my reverts, and am running a kernel that includes the
merge 972a2543e3dd ("Merge tag 'drm-next-2024-05-16' of
https://gitlab.freedesktop.org/drm/kernel") but I still see a lot of
warnings as per below.

I was going to say that the difference is that now they trigger
through the page fault path (amdgpu_gem_fault) while previously they
triggered through the system call path and amdgpu_drm_ioctl. But it
turns out it's both in both cases, and it just happened to be one or
the other in the particular warnings that I cut-and-pasted.

As before, there are tens of thousands of them after being up for less
than an hour, so this is not some kind of rare thing.

The machine hasn't _crashed_ yet, though. But I'm going to be out and
about and working on my laptop the rest of the day, so I won't be able
to test.

(And that kernel version of "6.9.0-08295-gfd39ab3b5289" that is quoted
in the WARN isn't some official kernel, I have about ten private
patches that I keep testing in my tree, so if you wondered what the
heck that git version is, it's not going to match anything you see,
but the ~ten patches also aren't relevant to this).

Nothing unusual in the config, although this is clang-built. Shouldn't
matter, never has before.

Arun is investigating and trying to repro it.  You still have a
polaris based GPU right?

Thanks,

We haven't been able to reproduce it across variety of GPU's. Would it 
please be possible
to send your dmesg logs and kernel config, I will check this on the same 
GPU you are using.

I just installed my RX480 polaris card in my AMD test machine, and
with current origin/master
I'm not seeing this at all.

Running an F40 GNOME desktop, doing firefox etc.

Linus, do you see it a boot straight away?

Dave.

Ok, back at that computer now, and yes, I see those messages right
away. In fact, they seem to happen before gnome even starts up, ie I
see those messages long before the first messages from gnome-session:

    May 17 12:07:17 tr3970x kernel: WARNING: CPU: 4 PID: 1067 at

    .. lots of warnings resume ...

IOW, it happens already during the graphical boot before I have even
typed in my disk encryption password.

Then it starts again when gnome starts.

I just checked: I have exactly 8192 warnings from the early boot
before the first gnome warning. Which sounds like too round a number
to be an accident.

I will try the patch Alex pointed at next:

    https://patchwork.freedesktop.org/patch/594539/

and see if that fixes it for me.

Ack. This seems to fix it for me - unless the problem is random and
only happens sometimes, and I've just been *very* unlucky until now.
