i've received word from a coworker that their trusty kernel (3.13.0-48-generic) is hitting this reliably as well
apport-collect fails for me: $ apport-collect 1437414 Traceback (most recent call last): File "/usr/bin/apport-cli", line 370, in <module> if not app.run_argv(): File "/usr/lib/python2.7/dist-packages/apport/ui.py", line 652, in run_argv return self.run_update_report() File "/usr/lib/python2.7/dist-packages/apport/ui.py", line 524, in run_update_report pkgs = self.crashdb.get_affected_packages(self.options.update_report) File "/usr/lib/python2.7/dist-packages/apport/crashdb_impl/memory.py", line 79, in get_affected_packages return [self.reports[id]['report']['SourcePackage']] IndexError: list index out of range -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1437414 Title: kernel unable to unmount loopbacks & leaks them Status in linux package in Ubuntu: Incomplete Bug description: run the attached script which: - creates a disk image - creates an ext2 fs in the middle of it - mounts that ext2 fs via loopback - deploys & runs some code in that mount - tries to unmount it the kernel ends up saying the mount is busy (it's not) and it's not possible to detach the loopback (probably because even with a lazy unmount, the kernel holds references to it) this is the utopic kernel 3.16.0-33 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1437414/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
