Public bug reported:

While running stress-ng on a ProLiant m400 Server I managed to cause the
disk controller to timeout which causes a file system hang. I am
wondering if the timeout was causes because I completely overloaded the
system causing it to be slow on ata handling times.

I ran:

stress-ng --all 64 -t 600 -v

and the machine slowly clogged up with stress processes, and finally hit
the hang.  Had to reboot the system.

Attached is a kernel log.
