Hello,

I use a atmel card AT91SAM9260 and I install Linux 2.6.25 with xenomai 2.4.4. I am doing a RTDM serial driver. I use the function rtdm_irq_request with the routine rt_rs485_interrupt. The interrupt number is 7. The interrupt is enable when a carracter is in the buffer Rx and the programm execute the routine rt_rs485_interrupt. But in my programm, when a caracter is in the buffer Rx, the programm doesn't execute the routine and I must reboot the linux. The console don't answer.

Have you got an idea of the problem? Thanks.

Séb.
