I installed Fedora 9 on a Dell Dimension 8100.

When booting, I encounter this:

Booting the kernel.
SMP mptable: null local APIC address!
BIOS bug, MP TABLE ERRORS detected!...
... disabling SMP support. (tell your hw vendor)
Red Hat nash version 6.0.52 starting
hub 1-0:1.0: unable to enumerate USB device on port 2

When I restart or shut down, this message appears:

localhost:login: mm-ststem-settings: Could not get the system bus. Make sure the message bus daemon is running! Message: Failed to connect to socket /var/run/dbus/system_bus_socket: Connection refused

Could someone please offer explainations for these messages?

I would check this out 1st

maybe this is the same error you are seeing

Thank you for the reference.

I haven't tried to compile anything or do anything with SMP (I get mail on my Mac), so I'm not sure that this is it.

More info: I got the same message with Fedora 8. I'm wondering if the kernel is looking for some connection to the network early and not finding it. I'm using a wireless card to connect to my home network.

Thank you for your interest.

I'm getting the same message ("... unable to enumerate USB device on port 2"), but nothing hangs and both USB devices (mouse and printer) work fine. FWIW, I first saw this the next time I booted up after a power failure; I don't remember anything in particular that I had installed, updated, etc. before then.

So far, since everything seems OK, I'm basically ignoring it except to think to myself, "Yep -- still there..." when I see it. If anyone thinks it's something serious, or if anyone knows how to get rid of it, I'd like to hear about it.

SMP=symmetric multiprocessing

In older releases there were two distinct kernel sets. One for multiple processors(X2,Dual core, etc) called SMP and one for single core cpus. Now they just use one for single and multiple cpus. IF you are using a single cpu this MAY just be indicating that.
