    It seems IRQF_SHARED | IRQF_DISABLED has already been discussed several
    times on LKML:

    <http://thread.gmane.org/gmane.linux.kernel/638251>
    <http://thread.gmane.org/gmane.linux.kernel/561205>

    Especially this message

    <http://thread.gmane.org/gmane.linux.kernel/561205/focus=561222>

    makes me think that Linus will reject my proposed patch for the lockup
    problem as it implements choice (c) on his list.


    Alan: should I try to implement his choice (f) insteadn, i.e. drop
    IRQF_DISABLED from USB HCD interrupts and disable interrupts in
    usb_hcd_irq() instead?

    Regards,

    Stefan
