    Hi
    I have old HP LH3 dual 400Mhz server which running mandrake Cooker. Any
    Kernel 2.4.X works fine on the system but any mandrake 2.6 or compiled
    kernel from kernel.org will panic on boot. I narrow the problem to IRQ
    routing since all 2.4 kernels will report my megaraid controller on IRQ 9
    and Intel EtherPro100 on IRQ 10 when 2.6 kernel reporting them on IRQ 25 and
    26 respectively. Are there any lilo switches I can use to make IRQs behave
    like under 2.4 kernel.
