gnome-power-manager frequently crashes with SIGSEGV in IA__g_closure_invoke() or g_closure_invoke()

[Chris Halse Rogers]

Binary package hint: gnome-power-manager

gnome-power-manager has been crashing fairly regularly for me. It seems to crash with this error everytime I start the laptop unplugged, but after starting it up again it seems to crash while plugged in, as well, just in ordinary use.

Looking at it, it seems like it might be crashing each time the percentage-charge of the battery changes.

Hm. It seems that sometimes, but not always, it spits some debug output before crashing.

I see the same thing; gnome-power-manager segfaults after a few minutes of runtime, even when the system is completely idle. I see the following output with --no-daemon --verbose before the crash:

** (gnome-power-manager:26090): CRITICAL **: gpm_cell_array_get_cell: assertion `GPM_IS_CELL_ARRAY (cell_array)' failed

and am attaching a complete --verbose log.

This may be a duplicate of bug 149746, but that bug is much older and had no further reports until this big spike in reports in Intrepid, so I suspect it's a different issue.

[Tobias Pflug (tobias-pflug)]

identical behavior here. SamsungQ45/64bit

[Albert Damen (albrt)]

Debugging manually with dbgsym packages installed gives a stacktrace with all symbols resolved.
#0 gpm_cell_array_update (cell_array=0x16d9380) at gpm-cell-array.c:288
#1 0x0000000000411d30 in gpm_cell_percent_changed_cb (cell=<value optimized out>, percent=85084016, cell_array=0x20)

In frame #0 length seems to indicate the number of batteries. That would mean length = 23939424 is wrong. My system has 2 batteries, as properly detected by hal:
$ hal-find-by-capability --capability "battery"
/org/freedesktop/Hal/devices/computer_power_supply_battery_BAT1 (main battery)
/org/freedesktop/Hal/devices/usb_device_46d_c50e_noserial (wireless mouse)

[Albert Damen (albrt)]

This bug is fixed in gnome-power-manager svn revision 2882:

* src/gpm-cell-array.c: (gpm_cell_percent_changed_cb):
The callback passes a gfloat, not a guint.

I applied the patch and gpm does not crash anymore.

[Olivier Cortès (olive)]

Hi, manually applyed the SVN rev 2881 (not 2882 !) 2-lines patch, and GPM is stable again. cool !!

gconf-editor still doesnt connect with gpm

Just happened to me on low power, I was doing nothing; laptop's unplugged. I'm on Intrepid Ibex AMD64.

[Rich (rincebrain)]

Not fixed for me, or apparently other people. Reopening.

[Rich (rincebrain)]

My apologies, a different bug is being encountered by everyone.

[Fernando Miguel (fernandomiguel)]

Rich how is this a new problem?
to me it has the exact same symptoms of the original bug.
It was fixed, and it restarted 2 days ago.
its even worse now, since running gnome-power-manager will not fix the power management or bright applet.
And since https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/242665 isnt fix either, i have to manually set my power setting by hand every time I change from battery to AC or vice-versa, inducing more crashes.

[amahfouz (eldood)]

yep, my problem is more or less the same.

Sorry, on further reading, my backtrace definitely refers to bug 269083. Moving myself over there.

[shirokuro (ccampbell1)]

The problem described initially on this thread is happening to me consistently on a clean-install of the released version of Ubuntu 8.10 (CD from .iso).

I am a newbie and don't have Linux debugging experience to know if the process/app crashes are the same phenomenon or cause, however the user-visible symptoms seem identical or very close.

 - on AC power, no problems.
 - on battery power, the below multitude of problems:
 - battery icon initially appears on menubar, but after some short time, becomes unresponsive
 - after the battery icon becomes unresponsive, try to launch Power Management from menus
 - power management app takes some time (sometimes a minute or two) to launch
 - when it launches, ALL mention of battery anywhere is missing (no battery tab, nor any other battery related options)
 - The screen brightness will sometimes dim. I have no way to control it.
 - Closing the laptop lid while the problem is occurring will not suspend the machine.
 - The problem will frequently recover automatically after some time (I haven't attempted to find the pattern)
 - By recover, I mean that the battery icon becomes responsive again, and the
 - Once the problem recovers, after some time, it will occur again (again, I don't know the pattern)
 - This goes on repeatedly (problem occurs, recovers, recurs)
 - The WORST symptom is, when the problem has recovered (battery icon responding, battery tab in control panel) if I suspend the machine (close lid) it goes into suspend fine. However, when I try to wake from suspend, the hard disk seems to go, it seems to wake up, however the screen remains completely off. I cannot get the screen to wake up and I have to force power-off the machine.

My machine is a Japanese Panasonic Let's Note CF-R3. These power symptoms do NOT happen on Ubuntu 8.04. Battery meter, control panel, suspend/resume all work perfectly on 8.04.

I tested both an 8.04->8.10 upgrade, and a clean 8.10 install. The power issues happen either way, although with the upgrade, the problem never seems to recover - once it happens once, it never recovers.

As I mentioned, I am an Ubuntu newbie, so I dont know how to gather the necessary data for people to work on this problem. If someone could let me know what data I need to provide, and how to get it, I would really appreciate it. These power issues are so critical for me, I cannot really consider Ubuntu 8.10 for serious use until it can be fixed.

Thanks a lot!

[Gert van Dijk (gertvdijk)]

I've got the exact same problems on my Thinkpad T61p as Craig.

It's fairly reproducible for me. Every time I plug or unplug the power cord I get the following message in syslog:
> acpid: client has disconnected
and gnome-power-manager becomes unresponsive. This also results in not being able to shutdown/suspend/hibernate from gdm and not being able to control the brightness of my laptop display from GDM (but works with function keys).

Sometimes even stranger things happen, like at this very time of writing, I get a second (identical) battery in Gnome Power Manger...

In Hardy I wasn't experiencing these problems.

Don't know to what extent this is related to the original bug report (I can make a new bug report if needed).

[Jared Johnson (jaredj-nmgi)]

getting this on current karmic beta. the automagical bug stuff led me here.

[Pedro Côrte-Real (pedrocr)]

Hit what appears to be this bug on latest lucid by unplugging the power chord. Hardware is a Lenovo X61 laptop. Anything else I can gather that can help here? Does apport even attach the crash info it collected to this bug report?

[basejumper9 (basejumper9)]

Same deal on a Lenovo X61 Tablet. Let me know if I can help out.

[Ilan (ilan)]

Seems to be occurring in Natty after waking from sleep.

[Stefan (sbossb)]

Got this error today after removing the power cord from my laptop. Running Natty Beta 1.

[Cristobal Tapia (crtapia)]

I'm having problems with when removing the charger using ubuntu 12.04 and gnome-shell. It is very annoying, because the computer don't respond anymore.

Any solution for this?
