Wrt. disk read failure in Colin's report, looks the sectors themselves invoved in timeout are good, becasue the following
test runs well in ms10-34 now:

    sudo dd if=/dev/sda skip=9741420 iflag=direct of=/dev/null bs=512
count=1K

Title:
  HP ProLiant m400 Server sda timeout causes file system hang

Status in linux package in Ubuntu:
  Triaged

Bug description:
  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.
