    Subject2.6.21-rc5-mm[12]: Oops on bootup in xor_see_2
    Date
    I'm getting this Oops when booting an 2.6.21-rc5-mm1 or 2.6.21-rc5-mm2 on an 
    Acer Aspire 1501 LMi in 32 bit mode (2.6.21-rc4-mm1 + hotfixes works
    perfectly):

    xor: automatically using best checksumming function: pIII_sse

    BUG: unable to handle kernel NULL pointer dereference at virtual address
    00000010
    printing eip:
    c02cb724
    *pde=00000000
