Hi,
This module is in localization /usr/lib/python2.6/popen2.py. There are
those two lines:
warnings.warn("The popen2 module is deprecated. Use the subprocess module.",
DeprecationWarning, stacklevel=2)
When you put hash ("#") at the begining those lines, warning should
not occur in the "free" command. For example:
#warnings.warn("The popen2 module is deprecated. Use the subprocess module.",
# DeprecationWarning, stacklevel=2)

Did you try with other discs? Are there any errors in "dmesg" log?
What error is reported after running this command?
Regards
