Description of problem: I'm running a Dell Optiplex 9010, with dual Samsung 840 Pro SSDs in software RAID 1. When I first boot up, everything is running as normal. However, within 15 to 20 minutes, all read and write performance to my drives drops to barely functioning levels. My IO monitors (I have kgrellm running) initially show throughput typically maxing out around 280MB/s, but they eventually drop to no more than 5MB/s. I haven't been able to wait long enough for a bonnie++ run to complete and get hard data. Version-Release number of selected component (if applicable): Extreme slowdown is reliably observed on my system in all 4.2 kernels. How reproducible: 100%. Steps to Reproduce: Just boot a 4.2 kernel, and wait. I'll be more than happy to try any troubleshooting steps that might either fix a problem with my setup, or shed more light on what the underlying cause might be. thanks!
