To: linux-kernel@vger.kernel.org MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, I am developing a linux device driver for a serial communication adapter which is based on interrrupt driven IO, top half handles registering the Immediate task queue and acknowledging to PIC, bottom half performs the actual task of interrupt handling. But after some period (may be after 2 –3 hours) recv interrupts are not coming (all other type of interrupts are Ok ..), If I reset the ISR0 (interrupt status register which contains recv interrupt) and enable ISR0, recv interrupts are coming. I would appreciate if you can help solving this problem. regards, Vvgkrishna_78@yahoo.com __________________________________________________ Do You Yahoo!?
