I also filed a sosreport upstream issue, because I believe sosreport shouldn't try to query "unused" block device such as loop device.
https://github.com/sosreport/sos/issues/1897 but situation remain that there is something going wrong with loop device and systemd/systemd-udevd at boot as explained above. ** Bug watch added: github.com/sosreport/sos/issues #1897 https://github.com/sosreport/sos/issues/1897 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1856871 Title: i/o error if next unused loop device is queried To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1856871/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
