Every few days/weeks I see Oopses like the attached one. I tried to track down the problem, but with added debug printk's the error didn't occur. I'm using em28xx and dib0700 based dvb sticks at an armv5te system (Marvell Kirkwood), the user application is vdr. Any ideas what is wrong or who can help here?
