VT-d related DMA errors

[Paul B Schroeder]

Hello all..

There seems to be an issue with the latest F-13 live CD on Dell 
Latitudes E5510 laptops.  i.e. It won't boot.  And it seems that it 
won't boot due to DMA errors.  These errors also show up in 
/var/log/messages when F-13 is directly installed on the system too.  So 
it's an issue in a non-live environment also.

The problem seems to go away when VT-d is disabled in the BIOS. 
However,  we're planning on deploying a custom live F-13 distro to a 
bunch of non-technical users on these laptops.  It would be very painful 
to ask each and every one of them to disable this in their BIOS.

So my question is:  Is there a kernel command line option or whatnot 
that I can use to get around the VT-d issues?  If so, this would be huge 
as I could simply build it into the live distro instead of asking the 
users to disable VT-d in their BIOS.

Thanks for any help...Paul...
