Done. I've also updated the product/component to Platform Specific/PPC-64 since
this wasn't an issue with amdgpu after all.

A nit, but might want to mark this bug as a regression and update the kernel
version to 5.2.1?

Here's the new patch that should restore the previous behavior correctly.

On second glance, it seems I got it backwards. pgprot_noncache /is/ actually
being set via the default implementation of arch_dma_mmap_pgprot, but this
creates the opposite issue. In the

Looks like this is a case where it's fairly critical to have a known 100%
reliable way to reproduce a bug like this. I'm bisecting further, so we should
be able to get to

Well, previously I had X11 running with 5.1.9 for ~2 weeks with no lockups;
then I rebooted into 5.1.17 and suddenly it locked up the second day with a
checkstop. Now back in 5.1.9, and

I just double checked -- 5.0.21 works, 5.1.0 does not. Daniel, didn't you say
your lockup was somewhat random? I can trigger this lockup every single time
with a specific

I actually haven't tested 5.1.9, but I can confirm that 5.0.9 works fine.

I see, I misread then, because the working kernel I have here is 5.1.9... I did
have it hang on 5.1.17, though.

That's strange. Both me and Shawn had 5.1.9 as a definitely working version.

I'm seeing this on 5.1.0 and up. 5.0.0+ was the last working version for me,
I'm continuing the bisect.

Maybe narrow it down first (i.e. find the last release that was good, by
testing 5.1.14 first, and then bisect only history between the last good and
first bad release. We know 5.1.9 is

Nevermind. Seems like I was able to hit the same problem today. It did not
happen on video playback though, just randomly, after about a day or two of
uptime.
