Hello @johannes-wuerbach Thanks for the suggestion. I had a look at the patch you suggested:
commit 2181e455612a8db2761eabbf126640552a451e96 Author: Anton Eidelman <an...@lightbitslabs.com> Date: Thu Jun 20 08:48:10 2019 +0200 subject: nvme: fix possible io failures when removing multipathed ns The patch was backported to 5.2.3, 5.1.20 and 4.19.61, so I went and tested it. I did a quick test by booting mainline 5.2.2, reproduced the issue, and then installed 5.2.3. I was able to reproduce the issue again, suggesting that this commit does not fix the issue. I then tried the latest 5.2.8, and also reproduced the issue. Just to be sure, I backported the commit to 4.15.0-58-generic, and tested again: You can find the test kernel here: https://launchpad.net/~mruffell/+archive/ubuntu/sf234512-test I was also able to reproduce the issue, and I am confident that this commit does nothing for this particular problem. Thanks for the suggestion! But in this particular case that commit is not the answer. I have opened a ticket with AWS, and they have confirmed that they know about the problem and have developed a fix for their cloud platform. It is currently being deployed, and deployment will take a few weeks to complete. You might have been lucky and received a patched cloud machine at the same time 4.19.61 came out, or it fixed another unrelated issue that had the same symptoms. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1837833 Title: EBS Volumes get stuck detaching from AWS instances To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1837833/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
