Default Re: Problem: sleeping function called from invalid context at include/linux/rwsem.h?

This is actually a kernel bug, iounmap() acquires and holds the lock in question; it's unclear if the warnings are related to the OpenGL problem(s) you're seeing. You can avoid the warnings and possibly improve reliability by rebuilding your kernel without CONFIG_PREEMPT.
