Red Hat Bugzilla – Bug 465320
Kernel 220.127.116.11-14 hangs immediately after nash on an aluminium iMac
Last modified: 2008-10-04 05:04:59 EDT
Description of problem:
The kernel hangs immediately with the following message
BIOS ERROR: MCFG memory af f000000000000000 is not ACPI reserved
Version-Release number of selected component (if applicable):
install a 18.104.22.168-14 kernel on a 20" aluminimum iMac.
Steps to Reproduce:
The system doesn't boot
No log files, no dmesg. Nothing. It is impossible to take some information, since the boot process doesn't even reach a phase in which it can access the disk.
It stays indefinitely there with the "Red Hat Nash starting" and "kernel alive" rows below the formerly reported error.
The previous kernel, on the contrary, (2.6.24.?) doesn't show the problem.
It starts perfectly.
Yesterday, while posting the bug, i wasn't in front of my iMac so i've been a bit unprecise about the kernel versions.
The faulty kernel is 22.214.171.124-29 (instead of ...-14 as stated) while the working one is the 126.96.36.199-108 (instead of the 2.6.24-... as stated).
The screen, immediately after the grub phase, displays the following lines:
<Top of the screen>
<Some GRUB lines>
Decompressing Linux... Parsing ELF... Done
Booting the kernel
PCI:BIOS BUG: MCFG area at f000000 is not reserved in ACPI motherboard resources.
i8042.c: No controller found.
Red Hat nash version 6.0.52 starting
<Bottom of the screen>
P.S. the line "i8042.c ..." used to appear also with the working kernel, therefore i suppose it has nothing to do with the hang.
Should be fixed in 188.8.131.52-45
