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?

Have you tried kernel 3.10? The Saucy stack? –  Braiam Nov 16 '13 at 14:34
Is that available via the repos? I thought only 3.2, 3.5 and 3.8 were currently available for Precise? –  fig Nov 17 '13 at 18:44
no, you are able to install recent one in precise wiki.ubuntu.com/Kernel/LTSEnablementStack –  Braiam Nov 17 '13 at 19:08
Thanks, that helpful; but what it appears to say is that right now only 3.5 and 3.8 are available, although shortly the saucy kernel and HWE stack will be available when the 12.04.4 point-release is out in January 2014. I think it is possible to install the saucy stack right now without the point-release, but I'll have to think if I'm willing to do that! –  fig Nov 18 '13 at 22:04
Edit: The xorg saucy packages dont seem to be available yet for precise. –  fig Nov 18 '13 at 22:06
