Same problem on my Dell inspiron e6410. According to a web search, the devices are: 04:00.0 CardBus bridge [0607]: Ricoh Co Ltd Device [1180:e476] (rev 02) 04:00.4 FireWire (IEEE 1394) [0c00]: Ricoh Co Ltd Device [1180:e832] (rev 03) (prog-if 10) I believe the DMA that happens at this moment is from the device 04:00.4 to main memory into a consistent buffer (self ID reception). Perhaps the kernel missed to set up the CardBus bridge correctly? discussion of the bug at linux-pci and linux-kernel: http://lkml.org/lkml/2010/5/22/69 I'm seeing this same thing... Turning on VT-d support on my Lenovo T510 keeps anaconda from being able to install, and turning VT-d support on *after* the installation fills /var/log/messages with DRHD and DMAR messages just like the ones above. I'm happy to help test changes if people would like me to be a guinea pig. Jared, what machine do you have and what does "lspci -nn" say about the FireWire device and about the device whose ID turns up in the kernel log messages? I'm having the same trouble on my Lenovo T410 (2522-AL3). Here are the 0d:00.* entries from lspci -nn: 0d:00.0 SD Host controller [0805]: Ricoh Co Ltd Device [1180:e822] (rev 01) 0d:00.1 System peripheral [0880]: Ricoh Co Ltd Device [1180:e230] (rev 01) 0d:00.3 FireWire (IEEE 1394) [0c00]: Ricoh Co Ltd Device [1180:e832] (rev 01) *** This bug has been marked as a duplicate of bug 605888 *** |
