I think 2.6.30 is recent enough to report upstream; they can ask to test a more recent version if necessary. It sounds like there's a problem with DMA from the ATA controller to memory above the 4 GB mark. The kernel is quite capable of avoiding that if the driver properly specifies the limitations of the hardware, so this is probably a driver bug. So it's important to know which ATA interface you have. If you don't know the answer to that, just include the output of "lspci -vv" in your report.
