Hello Alan,

  I did not check the RedHat bugzilla, but on the desktop machine once I 
removed "noapic acpi=off" the network card works no problem!

  So I put back the cards on the original server...

  Unfortunately there I have now "BAR 1 no parent found for of device 
bla bla" at boot and the process hangs when I remove those flags...

  This is a clearly a separate issue,  I'll see if I need to reintroduce 
some parameters on the boot command line..

  Thanks for the support..

Raimondo
