Bugs #14900, and #14728 look very suspiciously like they might be the same thing as well. I would be interested to see if commenting out: '#define USE_PCI_DMA_API 1' in drivers/char/agp/intel-agp.c fixes the problem for those bugs as well. I suspect that some better run time checking is called for here. Zephaniah E. Hull.
