commit 46ee8349d22d11ec4b8609c5bf14db9409eef974 Author: Gerd Hoffmann <kraxel@redhat.com> Date: Thu Jun 7 10:34:31 2012 +0200 update bios date Linux ignores some information from acpi in case the bios is old as acpi support used to be buggy in the early days. This affects ressources for example (unless forced with pci=use_crs). So lets go for something more recent. With this patch applied the ressources for \\SB.PCI0 will show up in /proc/{iomem,ioports}, tagged as "PCI Bus 0000:00".

Can we make the bios date set from fw_cfg? We really can't change the SMBIOS information unconditionally like this. Regards, Anthony Liguori
