    I fixed the double-oops caused by misaligned stack pointers, and the
    oops if kmem_cache_alloc is called with an misaligned stack pointer.
    In this case it seem to be an oops in the bios itself.

    Gary: did it work with 2.4? Are there any bios upgrades you could try?
    My guess is that the bios is just buggy.
