Public bug reported:
The system become unresponsive during disk access. I'm using Ubuntu
14.04 on a ThinkPad lenovo E540.
The steps I use to reproduce this bug is:
- install `stress` package
- stress the disk (# stress -d 2 --timeout 20s)
- during the stress test the system hangs while accessing disk from another
process (even ls hangs waiting the stress timeout)
