Awesome. Thanks. I can't test suspend in a VM, and I don't have a physical Ubuntu install.
The block developers arranged a more convenient test for the underlying issue in https://github.com/osandov/blktests/ Before (i.e. linux-image-4.15.0-23-generic): $ sudo ./check block/016 block/016 (send a signal to a process waiting on a frozen queue) block/016 (send a signal to a process waiting on a frozen queue) [failed] runtime ... 8.112s --- tests/block/016.out 2018-06-15 10:05:09.080764871 +0100 +++ results/nodev/block/016.out.bad 2018-06-15 10:05:27.236769759 +0100 @@ -1,2 +1,3 @@ Running block/016 +dd: error reading '/dev/nullb0': Input/output error Test complete After (i.e. 4.15.0-23.26~lp1776887): $ sudo ./check block/016 block/016 (send a signal to a process waiting on a frozen queue) [passed] runtime 8.112s ... 10.086s $ I don't see any problem with the patched VM, though obviously it would be nice to have someone test both normal suspend and the pm_test reproducer on a physical install. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776887 Title: Critical upstream bugfix missing in Ubuntu 18.04 - frequent Xorg crash after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1776887/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
