Thanks Mathieu; all your traces indeed have +++ killed by SIGHUP +++
which is from /usr/lib/udisks2/udisks2-inhibit. This is a race condition, when polkit gets killed at the wrong time while a request is pending it would behave that way. Curious that this only surfaces right now, /usr/lib/udisks2/udisks2-inhibit has been like that for a while already. All of your traces got interrupted in poll() though, i. e. there was no pending request (no recv* yet), so this did not interrupt a pending call. However, this is still bad. Thing to try on a machine which reproduces this: Please comment out all the code except the final "$@" from /usr/lib/udisks2/udisks2-inhibit (from initramfs break=casper-bottom) and verify that this crash then stops. Then, once you are in ubiquity, run "pkill -e --signal STOP gvfs- udisks" to stop gvfs-udisks2-volume-monitor (but that does not apply to all derivatives, such as KDE). I'll think about how we can inhibit udisks without having to restart polkit. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1508075 Title: ubiquity and others time out on polkit (killed by udisks2-inhibit) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udisks2/+bug/1508075/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
