请问一下USB问题
开机的时候停在hub.c: USB hub found
hub.c: 2 ports detected
usb-uhci.c: USB UHCI at I/O 0xffffffc0, IRQ 6
usb-uhci.c: Detected 2 ports
usb.c: new USB bus registered, assigned bus number 3
-------------------------------------------------------------------------
在irq.c中
request_irq->setup_arm_irq->spin_unlock_irqrestore
之后trace发现驱动停在
spin_unlock_irqrestore(&irq_controller_lock, flags);
这个函式.就过不去.
请问一下是哪边有问题???
