Hi, Has any one worked on Interrupt handling in PPC 405 for STBx25xx. I am working in interfacing USB devices for STB. The Device Driver is getting stuck or runs unconditional in calling ISR. I Identified that that the spin_unlock_irqrestore function call in the kernel does it. So i am unable to go ahead and could not find what to do further. If any one is aware or worked on this kind of problem plz help me.
