Bug Description
We have a PPC system on Ubuntu 16.04.1 LTS that will lock up if we issue a display or status command to the RAID controller during RAID rebuild process. The HDDs where the Operating system resides will change to RO (Read Only) once we trigger the problem. This will only occur if the Operating System's HDDs are also connected to the RAID controller. We've tried this problem with the OS residing on a USB and this problem does not occur.
