I'll throw in that it is still happening for me. Before, I was probably "lucky" enough to hit the gaps, both in observation and usage. Same symptoms, with or without VMs running, all CFQ scheduling. Not sure if HDD layout/config affects this, but maybe it'll help isolate the problem: 1x Corsair F120 120 GB SSD, primary OS drive 4x Seagate "green" 5900 RPM 2 TB HDD, in 2x 2-disk RAID-1 configuration (mdadm)
