Re: TOI and kernel 3.7-3.8 resume problem

Hi Federico,

I'm currently using ToI with a kernel 3.7 and it has been rock solid. I
have heard of some users having problems with 3.8... but I haven't tried
that myself.

Maybe it has something to do with your hardware? Do you use pm-utils? This
package has a history of causing hibernation problems, at least to me. It
is supposed to fix all kinds of power management problems, but has a lot of
corner cases for legacy hardware which end up ruining hibernation and
suspend for newer computers.

If you do use pm-utils, try installing the hibernate script (also a
sub-project of ToI). It takes some time to set up properly and a bit of
nosing with the config files, but it gets the job done beautifully,
especially when compared to pm-utils.

A quick way to find out if pm-utils is messing with your system is to try
hibernation via the command line. As root, do "echo /sys/power/state". Wait
for it to hibernate, and then resume. If it works without a problem, then
it's something to do with pm-utils or your configuration.

Regards,
Pedro
