I recently got an OCZ Vertex Plus SSD added to my system (12.04.3). It makes things super-fast. However, I sometimes get hang/freeze/lock-up of several minutes long where the SSD LED stays on and anything wanting disk access is blocked. The system recovers fully afterwards, and there is no sign of any issue in the logs. The problem exists with kernel 3.2.* and 3.8.*.
Searching the internet find many posts of similar issues in Windows 7/8 related to DIPM - a form or power management of SSDs. Disabling DIPM is recommended, but I don't find any text showing how to do that on Linux. How can I do this?
