Hello, I have tested and found this bug to occur on the specified bisected commit through Linux Kernel version 5.11.12. I am running Devuan (Debian) Linux with a hand created kernel config. I'm attaching it.
I've bisected the kernel and found the broken commit. Here's how I got there in case you're curious: for i in "start v4.19-rc1 v4.18" bad good good skip skip good good skip good skip good skip good good bad good good bad good bad good bad bad good; do git bisect $i; done
The broken commit is this one: commit 8eaf2b1faaf4358c6337785f2192055c6ef41e0d Author: Alex Deucher alexander.deucher@amd.com Date: Mon Jul 2 14:35:36 2018 -0500

The last few messages before the whole system, including the network part of the LK and USB subsystem of the LK freezes up/powers down are: #15 #16 #17 #18 #19 #20 #21 #22 #23
I think that's telling my that I have 24 threads in my 3900X.
During boot up, I don't even reach init. The whole system freezes. I don't see any boot up messages that suggest a problem with anything. I see only a very few massages at all. I did enable early printk.
Steps to reproduce: 1: Build kernel with my config on a bad commit. 2: Boot new kernel (with an AMD HD7770 GPU installed, of course). 3: profit.
If you even think of suggesting I upgrade to a newer GPU, recall also that there are none in stock -- and any GPU that is is priced unbelievably high. I'd love a newer GPU. But I'm going to have to wait like I have been for years for RDNA's big Navi (I was hoping it was compute/gaming oriented like a Titan. It looks like it's not. Grrrr, more waiting...)
Thanks, David
