A solution I have found is to add: reserve=FE000000-100000000 to the kernel command line. This will cause 512MB of addess space in first 1GB of addressing range to be left free for PCI devices. I thought the i875 chipset supported 64bit DMA so there may be a bigger problem here.

If I reboot with mem=850M this works. Am I out of address space for the video memory ioremap? Is there a kernel param to force more memory to be highmem? ===== Jon Smirl jonsmirl@yahoo.com __________________________________ Do you Yahoo!? Yahoo!
