The bge driver has seen quite few revisions in the last 6 months with varied 
reports of it working for some and not working for others.

It may be worth while providing the entire dmesg under current.

I have:

On a dell sc440 with:

Which previously didn't work ... and may still not .... best to test now I 
suppose ...

OK, it appears to be working but I'm sure when I configured a bridge and added 
the interface it was not responding, hence the reason I am still using an 
rtk0.

I'll try and test it further and if possible install the latest kernel but 
without putting it under load it appears to work. I know it's a different 
model but the entire BCM5x series has had issues so hopefully there isn't 
much left to tie up. With any luck, this info, combined with your dmesg 
output may aide someone in identifying the issue.

Also, just to note ... ioapic, acpi and smp can be buggy on a variety of late 
model systems ... assuming you are using a generic.mp kernel, disabling some 
may assist but I'd say ioapic is required based on my dmesg.
