I am finding sometimes when I "suspend" the computer and then wake it back (by pressing the power button) I am presented with a login screen and any programs which were running at the time of suspend are terminated. I have captured some differences in the system log when suspend fails and when it succeeds. I need some help in interpreting.
The suspend/unsuspend process generates about 200 lines of log starting with
Quote:
Jun 9 13:51:11 taylor12 kernel: [ 195.187118] PM: Syncing filesystems ... done.

and ending with

The failed evolution (when I was logged out) contains the following lines which are not present in the successful evolution

The successful evolution contains the additional line

Other that the differences shown above the logs differ only by a few duration values (a few milliseconds here and there) and one PID

Any kernel log interpreting gurus willing to take a look at this?
TIA,
