lspci triggers NULL pointer dereference on AMD Renoir laptop
Running Arch Linux with 5.8.0 kernel built from linux-mainline on a Dell G5 15
SE 5505 laptop with a AMD 4800H Renoir APU and 5600M discrete GPU.
On a fresh install of Arch, running lspci triggers an oops and NULL pointer
dereference. The oops is not triggered if the kernel is booted with
amdgpu.runpm=0, so it appears to be power management-related. The oops kicks
off with the following errors (full dmesg and lspci -vvv output attached):
[ 93.485414] [drm] PCIE GART of 512M enabled (table at 0x0000008000000000).

Can you bisect and determine what patch fixed it?

I am now unable to reproduce even on versions <5.8.6, which I know still had
the problem. So I am thinking it may have been a firmware update or something
else that resolved the issue for me.
