Taking Linux to the extreme: "Hey, it compiles.

Exactly the same behaviour here (I forgot to mention I tried this with the cpia cam too; didn't trust my own driver because of the many changes). NB: if the process is stuck in 'down_interruptible', why can't I stop it with ^C? Or is this IRQ interrupts we're talking about? - Nemosoft _______________________________________________________________ Have big pipes? SourceForge.net is looking for download mirrors.
