The above message means that an IRQ 7 occured, but nobody took care of it. Your ir_in_irq() function and its use of the "handled" variable looks a bit suspicious to me. Extract of Linux Device Drivers, chapter 10, page 272 : « You can also generate the return value with this macro: IRQ_RETVAL(handled) where handled is nonzero if you were able to handle the interrupt. » In your case, "handled" is always zero, so the Linux IRQ subsystem always thinks that you didn't take care of the interrupt.
