Comment 2 Josh Boyer 2013-02-11 13:09:43 UTC 
The atl1c driver isn't calling pci_dma_mapping_error to validate the pci_map_single calls it is doing.  I've emailed upstream:

Comment 3 Josh Boyer 2013-02-12 12:40:41 UTC 
Please give this scratch build a try when it completes.  It has a patch to the atl1c driver to fix the DMA API warnings and the DMA_API_DEBUG option set.

Comment 4 Fedora End Of Life 2013-04-03 19:29:31 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)
