Disabling IRQ #11

I upgraded my Fedora Core 1 system (Dell 4550) to Fedora Core 2.
What a disaster! Lots of stuff no longer works!
The biggest problem is that I get a message that says
"Disabling IRQ #11" and then the system hangs.
I can boot the system and login to the console as root and it pretty
much works. But if I login as myself (non-root) the system hangs
before my login completes.
I only see this message if I also login to the system as myself using
ssh from another system. The ssh window sees the message just before
the system hangs.
Under Fedora Core 1, /proc/interrupts looks like this:
CPU0
0: 901936 XT-PIC timer
1: 9611 XT-PIC keyboard
2: 0 XT-PIC cascade
3: 0 XT-PIC ehci_hcd
8: 1 XT-PIC rtc
9: 0 XT-PIC usb-uhci
10: 0 XT-PIC usb-uhci
11: 3272022 XT-PIC usb-uhci, eth0, Intel ICH4
12: 155723 XT-PIC PS/2 Mouse
14: 133430 XT-PIC ide0
15: 355117 XT-PIC ide1
NMI: 0
ERR: 0
(I had to fall back to FC1 to make the system useful, but I can boot FC2
and collect data as needed to debug this problem.)
Oh yes, I ran "yum update" and updated all the packages to the latest
versions. Made no difference.
Another piece of data... when I first booted Fedora Core 2 it ran
the hardware configuration wizard and claimed that my USB hub (or something
like that) had been removed. At first I told it to ignore this, but
after several reboots I told it to accept this change and remove it.
So, I suspect that this problem has something to do with the USB support,
but I don't know for sure.
Oh, I have *no* USB devices plugged into this system.
Any ideas what could be wrong, or what to do to track down the problem?
Why does this message only occur (and the system hang) when I login as
myself?
Thanks!
