Thanks for your confirmation, Julien. I have asked Ubuntu to import the proper fix from upstream and they responded very promptly. See:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1776887 They have posted a test kernel. I don't have a ubuntu install to test it on - only a VM which cannot suspend. It *might* be useful if someone wants to volunteer to try using the test kernel. You could test that your normal suspend still works, and test the command mentioned in the commit. I.e. $ sudo -i # dd if=/dev/sda of=/dev/null iflag=direct & \ while killall -SIGUSR1 dd; do sleep 0.1; done & \ echo mem > /sys/power/state ; \ sleep 5; killall dd # stop after 5 seconds On a "bad" kernel, any time you run this command it should show a message about an IO error. On a "good" kernel, the system will appear to suspend and resume, but there should be no IO error. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760450 Title: [nvidia] Xorg crashed with signal 7 in _dl_fixup() from _dl_runtime_resolve_xsavec() called from nvidia_drv.so To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1760450/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
