I went into the BIOS and selected:
Configuration
-> PCI Slot Devices
-> PCI IRQ Locking
-> Routing Algorithm [Smart]

Ok I changed Routing Algorithm [Smart] to [Fixed] and got a scary 
warning about data loss etc. but I hit Yes and saved as prompted and 
rebooted.

Ok hopefully I will have this LH3 "fixed" as well : )  

Thanks for the help.


P.S.  I have been looking at mailing list archives where the following 
was mentioned...  Is this going to be a problem?  Could this be causing 
my current problem?
