[nvidia] nvidia-435 crashes the kernel in gpu_i2c_master_xfer

[leogps]

The screen freezes but the mouse can be moved. SSH access works.

This is on Legion Y545, Ubuntu 19.10
Nvidia Geforce 1660Ti
Intel 9750h

Symptoms:
This only happens when: Nvidia-Prime is selected as "on-demand"
And maybe most likely after the laptop comes out of sleep.
xserver-xorg-video-intel is the latest :: 2:2.99.917+git20190815-1

If I choose prime-select "nvidia", this never happens. Makes me believe this has to do with intel video drivers.

The error messages in the nvidia-installer.log, I got fed up with this bug and upgraded my kernel to the latest, 5.4.x but nvidia--driver-435 does not recognize that kernel, so I purged kernel 5.4.x and went back to the older version.

[Daniel van Vugt (vanvugt)]

Your kernel log is showing a crash in the Nvidia kernel driver which may or may not be related:
[27603.845573] gpu_i2c_master_xfer+0xf5/0x23b [i2c_nvidia_gpu]

Also, if the mouse moves then that means Xorg is still working. It's only Gnome Shell that has stopped responding.

Please start by following these instructions:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.

[leogps (leogps)]

Hi Daniel,

The crash file I see is named "_opt_google_chrome_chrome.1000.crash". This makes sense because I remember the crash happened when I was browsing on chrome.
However, when I do `ubuntu-bug /var/crash/_opt_google_chrome_chrome.1000.crash`, a google-chrome dialog opens asking me to report it to google-chrome developers. I am not sure how to force it so as to report the crash here.
I will attach the crash file here. I might manually create a bug if needed in here with the crash file.

[Daniel van Vugt (vanvugt)]

When you say the screen freezes, are you referring to the whole shell or just the web browser?

P.S. We are unable to handle Chrome crashes here because Chrome is not part of Ubuntu. See also comment #3.

[leogps (leogps)]

The whole shell and this happened before when I am working with other software.
The mouse moves but nothing in the screen responds to mouse or keyboard input.
I logged into the system from another laptop via shell and was able to generate the bug report.

I followed comment #3 and it said the chrome crashes cannot be sent out to ubuntu. I will enable on-demand or intel(performance mode) and see if I can reproduce the issue.

Thanks.

[leogps (leogps)]

Ok. This happened again today. Again, it's google chrome. I am attaching the crash dump just for reference.
I will uninstall chrome and see if this happens with other programs.
I will send a bug report to chrome.

[leogps (leogps)]

This happened again without google-chrome in the picture.
Opened another bug via cli: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1856092

[Donjan Rodic (bryonak)]

Experiencing the same maybe once every two weeks for about two years now.
When tabbing in or out of Chromium, the GUI freezes. The mouse cursor moves, but clicking does apparently nothing.
The keyboard works: space bar to pause/resume music if a player was focused, as well as switching to a virtual terminal. I can log in there and kill X / restart gdm3, but the GUI session is lost.

$ cat /etc/issue
Ubuntu 18.04.3 LTS

$ prime-select query

Here's a heavily snipped journal (removed media key/spacenavd/network mount warnings and excess repeats) from around the crash:

[Daniel van Vugt (vanvugt)]

Thanks but crashes in Chromium should ideally be dealt with as separate bugs. This is a Gnome Shell bug.

Please reproduce the freeze again, then reboot and immediately run:

  journalctl -b-1 > prevboot.txt

and attach the file 'prevboot.txt' here.

[berglh (berglh)]

I'm experiencing the same issue as the OP. Here is the requested 'pevboot.txt'. It's happening for me multiple times during the week - I'd say two to three times a week on Ubuntu 19.10.

gnome-shell 3.34.3-1ubuntu1~19.10.1
nvidia-driver-440 440.59-0ubuntu0~0.19.10.1

[Bjorn Hassler (bjohas)]

I'm experiencing the same issue. Similarly, around 3 times a week on Ubuntu 19.10.

[Donjan Rodic (bryonak)]

@vanvugt: I haven't described a crash in Chromium. But I have switched away from Chromium, the frequency of Gnome Shell freezes it induces being one of the reasons. Attached is a journal from a freeze that happened today, with Firefox and VirtualBox open (and some filebrowser/terminal windows).

[Daniel van Vugt (vanvugt)]

Everyone other than the original reporter, please open your own separate bugs.
