So this is pretty much the same issue as my post on the old forum regarding "Weird CPU management". For those that didn't read it, I was reporting an issue about how one CPU core was almost always at 100% utilization while the others were mostly idle. By running "cat /proc/interrupts", I was able to discover a ton of interrupts on one core corresponding to "rtl_pci".
Here's what's new: fortunately, I think I've narrowed the issue down to the wifi card/driver, and I'm almost certainly positive that that's what's causing my high CPU issue.
Right now it's no longer irritating me as much, since all I need to do is toggle my wifi off and then on to fix the issue. Although, it would be great if this could be fixed.
I'll be more than glad to provide more info about the situation. Thanks!
