Bug Description
Binary package hint: linux-image-
Directly after GRUB there comes this message just before the splash screen is shown:
[ 23.873968] PCI: BIOS Bug: MCFG area at e0000000 is not E820-reserved
[ 23.874166] PCI: PCI BIOS revision 2.10 entry at 0xf0031, last bus=1
[ 23.938788] PnPBIOS: Disabled by ACPI PNP
And after booting dmesg shows very often things like "[15549.240000] APIC error on CPU0: 40(40)" very often.
Both messages I don't receive under Feisty but under Gutsy
There are also problems with ata2 as you can see in the dmesg-log. And I can't understand why SCSI-emulation is used. Is this neccessary or a bug? On the boot cd it isn't used and under Feisty either.
Maybe there's a relation that my network deviced are called lo, wlan0, eth2 and eth3 instead of lo, wlan0, eth0 and eth1 as it is under Feisty
My System is a ASUS Notekook A6Km with an AMD Turion64 ML-37.
Maybe the "bcm43xx"-module produces the APIC errors. On Feisty I had blacklisted this module and used ndiswrapper instead.
But what does that BIOS bug mean?
