Comment 36 for bug 568120

Telling people to use the "newer hdparm from Debian" doesn't help fixing this issue. Using the same package version of hdparm from Debian as is in Ubuntu will work too, as nothing got fixed in the newer version, and the fact that it works is only because Debian still uses a legacy method. What we need to figure out is why for some people it doesn't work with the new methods used in Ubuntu.

@daniel_L: I think 's2ram' isn't supported in Ubuntu? Are you sure this isn't a bug in that software?
