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).
