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?
