So the issues as I understand them: o some BIOSes are broken and don't properly map MCFG space (though according to Petr V. reserving MCFG space in e820 is optional, so the test may be slightly wrong as-is) o MCFG space is required for (many) PCIe devices (any regular PCI devices?) o often, there's nothing the user can do to address the points above
So where does that leave us? I've got what I consider to be a stupid error message in my log. My system behavior isn't affected in any way (at least that I can tell), yet I get a loud complaint at boot time.
I guess I just have to live with it?
Thanks, Jesse
