    I'm not just unhappy to be unable to control the IRQs with the bios
    anymore, sym53c8xx doesn't want to share IRQs with the usb
    subsystem in this case... (kernel panic (killing interrupt handler(?))
    and reboot (rebooting in 60 seconds))

    2.4.0-test9 behaviour was different. It really used what the 'bios
    box' stated during bootup. - A way to set the IRQ distribution via
    kernel-params is okay for me, too.

    I'm native German - what is 'failure mode'?

    2.4.0-test9 agrees with the bios. [Currently I gave my VGA card (the
    S3) an IRQ - without one in the bios 2.4.0-test9 was happy, but 2.4.0
    gave it IRQ 8 on its own.]

    Okay. For 2.4.0-test9 it's following immediately. After that a
    diff of "lspci -vvx" from 2.4.0-test9 to 2.4.0 is included.

    Full "lspci -vvx" are in my original post:
    http://boudicca.tux.org/hypermail/linux-kernel/latest/0130.html

    To mention it: I have also an ASUS SP97 like Aaron Tiensivu. But the
    XV version with (unused) onboard VGA.

    Further I always see '09' in the Configuration Space at Interrupt_Line
    (0x3c) for the 00:01.2 USB Controller. But 2.4.0 says:
    Interrupt: pin A routed to IRQ 12
    while 2.4.0-test9 states:
    Interrupt: pin A routed to IRQ 9

    Please tell me if it helps te see a "lspci -vvvxxx" from 2.4.0 and
    whether I should give some 2.4.0-test?? a try...
    I must go to bed now - otherwise my mother kills me when she reads
    linux-kernel tomorrow... (-:
