Yes, and the problems that occur are usually related to the USB subsystem, based on things I've heard about with other software I run.

And, yes, AMD and Intel have both had an occasional "oops" impacting a specific CPU series. In my experience, most of these "blame" issues arise from really poorly designed/buggy motherboards. Unfortunately, in practice, more of these bad boards seem to be found in low-end AMD boxes, where system builders are cutting every cost corner. With a good quality MB, AMD and Intel CPU's both work great and exhibit similar reliability/stability....And, in case you're wondering, I run a Co-Lo center and have a few racks full of AMD boards! I measure up-times in years. 73, David KB4FXC On Wed, 11 Sep 2013, Andreas Pleschutznig wrote:
Huh? Now you see me stumped. I can see some badly designed math library having a problem with that, but what does that have to do with the processor. I am not discounting the statement, just trying to gather information, and the statement does not just come through the filter I have in my brain as to makes sense.
As far as the CPU goes, yes I do have an AMD chip:

Any chance you are using an AMD processor? If you tx tone and your voice are more than 999 combined, that could also be the problem.

Sounds to me like a computer with too little RAM or too little CPU horsepower.
When you run the top command, is it using swap memory? If so, that's bad...and you need more RAM.
