--- Comment #54 from John Baldwin <j...@freebsd.org> ---
I think the patch is probably fine. This looks to be a BIOS bug. The failing
memory BAR for the VGA device is '0xfeb00000' with a size of 256K. However,
ACPI reserves the first page of that range as a system resource (from devinfo
-vr output without the patch):
nexus0
...
acpi0
...
I/O memory addresses:
...
0xfeb00000-0xfeb00fff
FWIW, hw.pci.realloc_bars is a bit of a conservative knob that I had considered
enabling by default. I've added Warner to see what he thinks about possibly
enabling this knob by default in HEAD. The current patch is probably fine to
commit as-is and is probably safe to MFC as well since it is specific to that
device id.
