    Subjectwbsd: IRQ handler type mismatch
    I'm seeing this on bootup on my laptop with recent kernels (currently 

    Floppy drive(s): fd0 is 1.44M
    IRQ handler type mismatch for IRQ 6
    current handler: wbsd

    floppy0: Unable to grab IRQ6 for the floppy driver

    It looks like wbsd is being loaded first, which being a nice PnP device
    sees that IRQ 6 is available and grabs it. Then the we try to load the
    floppy module (which is hard-coded to use IRQ 6) which fails because
    wbsd already owns IRQ6 (which is fine, there's no floppy controller
    anyway). The mismatch is occurring because wbsd passes IRQF_SHARED
    whereas floppy doesn't. I assume one of the two is likely wrong. Should
    wbsd really be passing IRQF_SHARED here? This is an LPC device which
    uses ISA-style edge triggered interrupts, is it safe to try and share an
    interrupt with this chip anyway?
