Very high disk access time spikes under heavy usage #625

I have a disk with one btrfs partition mounted to windows. After a while of heavy usage, it seems that the average disk access times for the drive will skyrocket in a strange fashion. All disk i/o will cease for upwards of ~15 seconds, then resume as normal with good speeds and such. Any software that used the disk will lock up until it comes back, which it sometimes may not. Task Manager reports average response times of ~60k ms when the disk comes back after the lockup. The system has never encountered a BSOD due to this, however. Rebooting temporarily fixes the issue until the disk is used heavily again, where it comes back. I don't know what logs I should be sending, if any, so an emphasis on that would be helpful.

If it happens again, set Windows to "High Performance" in the Control Panel and then let it know.
