After more searching I have found solution in Bug #571038 - https://bugs.launchpad.net/ubuntu/+source/gnome-disk-utility/+bug/571038
Package that causes troubles - udisks Symptoms: # gvfs-mount -l (gvfs-mount:7200): GVFS-RemoteVolumeMonitor-WARNING **: invoking IsSupported() failed for remote volume monitor with dbus name org.gtk.Private.GduVolumeMonitor: org.freedesktop.DBus.Error.Spawn.ChildSignaled: Process /usr/lib/gvfs/gvfs-gdu-volume-monitor received signal 6 #gvfs-gdu-volume-monitor libgdu:ERROR:gdu-pool.c:2369:device_recurse: assertion failed: (depth < 100) Problem: Problem is explained in linked bug by Mikhail Titov, comment #28 - https://bugs.launchpad.net/ubuntu/+source/gnome-disk-utility/+bug/571038/comments/28 Cause of the problem is somehow "broken" partition table that udisks cannot parse properly. Udisks reads partition type 5 instead of real partition type and this leads to recursion. Solution: What solves the problem is patch from Mikhail, all steps explained in comment #46 - https://bugs.launchpad.net/ubuntu/+source/gnome-disk-utility/+bug/571038/comments/46 Bug report was submitted to udisks, not solved since current version is 2.0.* and Ubuntu is using version 1.0.4 Would you, Ubuntu guys, make patched version of udisks (using Mikhail's patch) available through your repositories? Many "automount not working" bugs as well as some other bugs like palimpsest might be influenced by this bug. ** Package changed: gvfs (Ubuntu) => udisks (Ubuntu) ** Changed in: udisks (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1093901 Title: Does not automount hotplugged storage device - no USB, no CD/DVD To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udisks/+bug/1093901/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
