Description Lex V. Ross 2006-12-22 03:29:23 UTC
Most recent kernel where this bug did *NOT* occur: 2.6.12
Distribution: Debian Testing (Etch)
Hardware Environment: Dell Inspiron 5000 laptop
Software Environment: KDE
Problem Description: Resume from s2ram takes anywhere from 50s to 1mi, during 
that time the screen is blank with flashing cursor in the top left-hand corner. 
At the end, the screen flashes briefly, goes completely dark twice, and the 
system is finally resumed. Sometimes synaptics touchpad does not work after 
resume (not responding to tapping, no scrolling features) but thebuttons at the 
bottom of the touchpad do.

ACPI gives the following error messages on resume from s2ram.

There is no problem with standby mode (quick and clear resume and so on). and 
stanby looks just the same as suspend to ram: stopped disks, blinking "power" 
LED etc.

Steps to reproduce: as root, run "s2ram -f" command. Different ACPI options 
make no difference.

Please look into #7466 and #7648 and try the latest mm kernel.
