Public bug reported: Since the upgrade to kernel 4.10.0-24, I'm noticing brief (several second) system non-responsiveness when disk activity is moderately intense. The level of intensity required is only, say, rsync'ing a day's photos from a mini-SD card (/dev/mmcblk0p1) or rsync'ing a directory from SSD to a server.
The system logs are not showing errors.
