chromium-browser crashed with SIGSEGV in content::GpuWatchdogThread::DeliberatelyTerminateToRecoverFromHang()

[James Mazur]

I was using Google Maps and Chromium froze up and crashed. After this, rendering of the new Google Maps page causes jagged lines to appear in the browser page display section, until I reboot the computer. Killing and relaunching Chromium doesn't fix the problem. The jagged lines still appear after computer reboot if I visit Google Maps again, and again won't disappear until I restart the computer.

James, does the proposed chromium in this PPA behave better?

https://launchpad.net/~canonical-chromium-builds/+archive/stage

[James Mazur (jamesmazur6)]

Yes. Oddly enough, before installing the PPA, I tried from the same
version of Chromium as when the bug occurred, and Google Maps was working
again. So I don't think it was necessarily a problem with Chromium. I
tried it with the version from the PPA, too; Google Maps was also working
on there.

Chromium still seems to be having problems with the Google Maps site. Now my entire system locks up when I do a search; I have to hold down the power button on my laptop to turn it off. I'm in "Version 31.0.1650.57 Ubuntu 12.04 (31.0.1650.57-0ubuntu0.12.04.1~cm1precise1)" of Chromium right now.

[Chad Miller (cmiller)]

James, when you see that happen, please log-in after it restarts and paste what is in /var/log/kern.log with time just during the crashing.

[Chad Miller (cmiller)]

Thank you, James. That log is frustratingly quiet. It looks mostly normal
until it is filled with zeros. It's doesn't help me much.

The last line is kind of interesting. Cups, the print service, tried to do
something that the security policy didn't allow. IF you're having problems
with that too, you might file a bug and attach that. I'd title it "cups
apparmor profile denied 'block_suspend' capability".

I'm not having any problems with printing.

I ran the bug again and this time the log came up without the zeroes in it. So that might have been a fluke, because my system locked up completely as normally (no response to any keyboard / touchpad action, at all). There were also no lines from the past 10 minutes before the crash, which would have included when I first started Chromium and when I first visited the Google Maps page.

I also played music in the background to see what would happen...it turned out that the same half-second of the song kept being repeated over and over again...it sounded like a broken record, or a skip in a CD. Maybe the fact that the music didn't just stop gives a clue?

Finally, I figured out what in particular seems to cause the lockup. It is not just visiting Google Maps, or even just panning and zooming after doing a search. It's, weird as it sounds, zooming out after having been zoomed in very close.

[James Mazur (jamesmazur6)]

One other thing -- there is a noticeable period, a few seconds in length, after which the Google Maps screen locks up, but I can still move the mouse. I just tried having System Monitor open next to Chromium so I could see what happened to the RAM/CPU usage when Chromium froze up, but, interestingly enough, the System Monitor line graph froze up at the exact same time as the Google Maps screen, even during the period in which I could move the mouse. BUT the music I was playing in the background continued normally in the few seconds I could move the mouse. So perhaps it is something with drawing that is causing the crash? Though it would have to be pretty general, as re-drawing in both System Monitor and Chromium froze up. Yet not so general that it stops the cursor from being redrawn.

[Chad Miller (cmiller)]

The zeros was definitely a fluke. The disk operations of adding to the file
and updating the size was interrupted in the middle somewhere.

Status changed to 'Confirmed' because the bug affects multiple users.

@James: are you still seeing this issue with recent releases of chromium?

[James Mazur (jamesmazur6)]

I don't have any way of verifying this since I don't use chromium anymore,
sorry.

Closing now as this report wasn’t investigated timely and is now too old to be meaningful.
Please do not hesitate to report crashes occurring with recent releases of chromium-browser, they will hopefully be investigated and acted upon in a more timely manner.
