MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii List-Id: Linux on Embedded PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi all, I am working on a character driver for FPGA, in which i am using a blocked read call on workqueue. The read call will be unblocked by the Interrupt from the Fpga to PPC Cpu. The problem is that if the process is in blocked mode and then an Interrupt occurs the system gives kernel Panic where as it get unblocked and start reading the data but very soon it gets crashed. Please send me your suggessins regarding the mentioned problem.
