Red Hat Bugzilla – Bug 253493
Last modified: 2007-11-30 17:12:13 EST
Description of problem:
The first mesages I get when booting linux is:MP-BIOS bug: 8254 timer not
conected to IO-APIC
I have previously just ignored this since my system work just fine, but in the
later kernels I recive PCI:BIOS bug:MCFG area at e0000000 is not E820 reserved.
PCI:Not using MMCONFIG.
I tryed testing with the latest kernel from the updates-testing repo, but the
problem is still there.
Version-Release number of selected component (if applicable):
reproduces everytime on my ASUS A7D
Steps to Reproduce:
Errors come up
MP-BIOS bug has bothered me all the way trough fc6 and until now the two others
has poped up with the latest kernel releases in f7 and are still there with the
kernel from the updates-testing kernel 22.214.171.124-57.fc7
These are just informational messages. First up, your BIOS is semi-broken, so
the kernel just lets you know. Since the MCFG area isn't E820 reserved, we let
you know that we're not going to enable MMCONFIG for your system. Nothing here
that is a kernel bug.
Thanks, one less thing a idiot don't have to worry about. Is this new functions
since previous kernels did not inform me about this?
If I'm thinking of the right bits, MMCONFIG was off in recent kernels, but we
turn it back on once in a while to see if it doesn't cause problems. I believe
the problem we usually run into is that it doesn't get disabled where it isn't
safe, but the correct action seems to be taken on your system.
