Subject: 3.2rc1: bootup fails: DRHD: handling fault status reg 2

Hi,

when trying to boot kernel 3.2rc1 on my thinkpad t510 I get an endless loop of errors:

 DRHD: handling fault status reg 2
 DMAR: [DMA Read] Request device [0d:00.0] fault addr fffff000
 DMAR: [fault reason 02] Present bit in context entry is clear

screenshot can be found here:

kernel 3.1.1 is booting up flawlessly.

Any idea?

Best regards
Arnd
