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
