Subject: dmesg full of DMAR errors

Hi,
I'm facing the same problems as described in
https://bugzilla.redhat.com/show_bug.cgi?id=605888
I'm not sure what the conclusion of the bugzilla discussion is:
1) you decided to not workaround the bug and I should disable VT-d instead
2) you decided to workaround the bug by blacklisting device IDs
The messages are:
DMAR:[DMA Read] Request device [04:00.0] fault addr fffff000
DRHD: handling fault status reg 2
The devices in question are:
04:00.0 SD Host controller: Ricoh Co Ltd MMC/SD Host Controller (rev 03)
04:00.4 FireWire (IEEE 1394): Ricoh Co Ltd FireWire Host Controller (rev 03)
or
04:00.0 0805: 1180:e822 (rev 03)
04:00.4 0c00: 1180:e832 (rev 03)
Product ID 0xe832 is not mentioned in the bug. Maybe it has not been
blacklisted if you went for (2)?
Regards,
Sven Köhler
