irq 16 nobody cared (try booting with irqpoll option)

[Edward M]

Hello,


Periodically, when i first boot my fedora system it hangs on this message:

[0.771697] irq 16: nobody cared (try booting with the irqpoll option)
[0.771823] handlers:
[0.771838] [<ffffffff8147ba40>] usb_hcd_irq
[0.771859] Disabling IRQ #16

  i need to reset system to get fedora boot
now i would like to try using the option, so how do I boot with irqpoll
or is there another way fixing this?


thanks
