This patch fixes an issue that the following error is
possible to happen when ohci hardware causes an interruption
and the system is shutting down at the same time.
[ 34.851754] usb 2-1: USB disconnect, device number 2
[ 35.166658] irq 156: nobody cared (try booting with the "irqpoll" option)
Hi Greg, Alan,
I'm afraid but, I would like to recall this patch because
I lacked the last sentence in the commit log.
I'll submit v3 patch soon.
Best regards,
