Bug#1041195: resource sanity check: requesting [mem …-…], which spans more than PCI Bus 0000:00 [mem …-… window]
Package: linux-image-6.1.0-10-amd64
Version: 6.1.37-1
In the depths of my journal I discover the following two warnings (last
two lines are marked orange):
Jul 15 15:21:43 AnonymizedMachineName kernel: radeon 0000:01:00.0:
vgaarb: deactivate vga console
Jul 15 15:21:43 AnonymizedMachineName kernel: sd 2:0:0:0: [sdb] Attached

Jul 15 15:21:43 AnonymizedMachineName kernel: [drm] initializing kernel
modesetting (VERDE 0x1002:0x6825 0x1028:0x053F 0x00).
Jul 15 15:21:43 AnonymizedMachineName kernel: resource sanity check:
requesting [mem 0x000c0000-0x000dffff], which spans more than PCI Bus

Jul 15 15:21:43 AnonymizedMachineName kernel: caller
pci_map_rom+0x65/0x180 mapping multiple BARs
lspci tells us this (hopefully this is the right place to look):

What are the extent and the implications of the warnings "resource
sanity check: requesting …, which spans more than PCI Bus 0000:00 …" and
“caller pci_map_rom+0x65/0x180 mapping multiple BARs”? Any
misconfiguration? Any adjustment options the kernel might need? The
machine is a Dell Mobile Precision M6700 with the processor Intel Core
i7-3720QM, 32 GB RAM, and AMD FirePro M6000 Mobility Pro graphic chip
with 2GB GDDR5.
Gratefully,
