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

drm/amdgpu: switch firmware path for SI parts
Use separate firmware path for amdgpu to avoid conflicts
with radeon on SI parts.

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
