That bolded text is part of the problem.
Unfortunately, and not to be hurtful, because -Current is always in a state of flux with updates pinpointing the exact cause it hit or miss. You should be using only the latest official release if you use a proprietary driver. Otherwise, sticking to the open source driver is the only way to know what exactly the problem is.
We can try to pinpoint it, but it might not be 100% correct...
Can you post the readout of the following diagnostic utilities?
