This isn't a show-stopper, but it's possible you'll get others running into the issue that understand as little as I did about it... Maybe this will save folks the hair tearing frustration I went thru tracing it. AMD64 > 4G memory: SCSI formerly (2.6.15 and earlier) used bounce-buffers. It now relies on the IOMMU, either the hardware GART IOMMU for true AMD64, or a software emulation thereof for Intel's EM64T. It'll need to be configured into the kernel and working. Also, here, I had a BIOS issue. AGP Hypertransport Fast-writes had to be disabled in ordered for the IOMMU (and DRI/DRM) to function. Because the kernel froze every time I tried IOMMU, I had the kernel configured without it, so I had /two/ changes to trace down and make, before it would work, thus the problem, since either one alone wasn't enough. -- Duncan - List replies preferred.
