Subject: BUG?: "Cannot map mmconfig aperture"
I get the following new message in my dmesg:
[ 0.155476] ACPI: bus type pci registered
[ 0.155567] PCI: Found Intel Corporation 945G/GZ/P/PL Express Memory Controller Hub with MMCONFIG support.
[ 0.161149] PCI: Cannot map mmconfig aperture for segment 0
[ 0.161181] PCI: Using configuration type 1
[ 0.165980] ACPI: EC: Look up EC in DSDT
when previously i'd have:
[ 0.156577] PCI: Found Intel Corporation 945G/GZ/P/PL Express Memory Controller Hub with MMCONFIG support.
[ 0.166403] PCI: Using MMCONFIG at e0000000 - efffffff
[ 0.166407] PCI: Using configuration type 1
[ 0.171548] ACPI: EC: Look up EC in DSDT
No idea if this is a regression or not, or what it means, the system works well.
git-bisect says the problem cames from:
commit c31c7d4844ea4817692ae16bf70f9c96c05a50eb
