GPU Coredump on 6.18.1 this morning.

GPU: RX 5700 (Navi10)
Distro: Arch Linux 

Hello,

I've been getting ring gfx timeouts, ring comp timeouts, GPU resets, and the
like (see my attached coredump) on any kernel after 6.17.9 during certain
gaming workloads. In order to rule out userspace graphics regressions, I did
test several Mesa and Proton versions.

I tested kernels:
1. 7.0.1-zen (bad)
2. 6.18.34-lts (bad)
3. 6.18.1-arch (bad)

but rollbacks to 6.12.75-lts and 6.17.9 did not reproduce any of my issues,
hence my suspicion that it is a regression of some sort between 6.17.9 and
6.18.1.

During my testing, I did find a faulty RAM DIMM and removed it from my system,
as well as reinstalling all of my packages and running a fsck to ensure no
corruption was the cause, but I did not alleviate the issues.

My GPU Coredump is attached in a compressed .tar.gz format due to file size.
Let me know if anything else is needed, and I'll update as it is.

Thanks
