Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Libera.chat.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/2062426/+editstatus and add the package name in the text box next to the word Package.

[This is an automated message. I apologize if it reached you inappropriately; please just reply to this message indicating so.]

[Rob Somerville (linuxgreybeard)]

Can't ascertain if this is a kernel fault or a driver issue, have tagged it as NVIDIA driver issue as drm_gem_shmem_helper.c is part of GPU drivers.

[Launchpad Janitor (janitor)]

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

[garyx (garyx)]

I seem to be able to get this crash consistently after locking the desktop and after a little while I come back and the session has crashed.

Need to reboot usually after this. Same nvidia driver version 550. Up to date 24.04 install.
