** Description changed: Binary package hint: gnome-power-manager Distro: DISTRIB_ID=Ubuntu DISTRIB_RELEASE=8.04 DISTRIB_CODENAME=hardy DISTRIB_DESCRIPTION="Ubuntu hardy (development branch)" Package: gnome-power-manager Version: 2.21.92-0ubuntu1 Problem: My laptop computer (Clevo D400S / Intel P4 1.8GHz / SiS 650 Chipset) has strange behaviour in Ubuntu 7.10 and 8.04 when suspending. I have experienced lockups on some resumes usually 1 of 3 and narrowed the behaviour by extensive testing and here is how I can reproduce it: 1. I startup the book on battery; 2. I suspend after loaded to desktop; 3. Then when suspended I plug in the AC; 4. I resume it; 5. Everything goes fine; 6. And here if I unplug the AC my book locksup; There is no output in /var/log/syslog or kernlog, and the suspend log goes normal. I have tested this with the stock 7.10 kernel, as well as with Debian's 2.6.24 kernel and same story repeats. What I discovered is that if I kill gnome-power-manager after step 5 and before step 6 - there is no lockup and system continues to function properly. If I restart it after killing it - everything continues to work properly. I decided that I will try to upgrade to 8.04 and see if this has been fixed - and indeed there was no such problem with 2.6.24 , but gnome-power-manager didn't measure battery at all only #acpi did. Then I started 8.04 with the 2.6.22 kernel and gnome-power-manager measured everything fine but the initial problem reappeared. Now I am not totally sure that the bug is in gnome-power-manager or in the connection between that and the acpi system or in the kernel itself. But it looks like the rest of the system works fine if gnome-power- manager doesnt interfere too much with it (8.04 + 2.6.24). I hope it is an isolated problemon my machine - I will just execute a script to kill and restart g-p-m on resume but if it is a bug it needs to be fixed imo. + + + 04 Mar | Update: + + After yesterday's updates (2.6.24-10 to 11): + 1. g-p-m detects battery life correctly. + 2. lockups are back as well.
