    Maybe memory fragmentation? Perhaps the driver tries to allocate a
    large block of memory and cannot find a continuous block of the right
    size.

    Maybe the driver developers used different kernel .config options than
    you are using.

    Try increasing the value in /proc/sys/vm/min_free_kbytes.

    Try switching some things like SLAB or SLUB, try booting with
    kernelcore=512M to enable the Movable memory zone, or try 64-bit vs
    32-bit kernels.
