When mounting and then unmounting a PV guest image (file based), the umount command seems to do the unmount but hangs and never returns. Subsequent umounts on the system fail including when the machine is shutdown. I have included a script demonstrating the hang. This bug may be related to Bug 666161 - cannot umount loop mounted image by image name. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Charles, could you please check if the kernel where this is happening has the following fix: ====== * Mon Jan 31 2011 jslaby@suse.cz - block: loop queue_lock null pointer derefence in blk_throtl_exit v3 (bnc#666598). - commit cd38efd ====== If not, please install kernel packages with this fix and try again. The package should be at least in 'Kernel:stable' repository and soon also in Factory (maybe already there). If you can still reproduce: is there anything in kernel log? Thanks in advance. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Once the issue has been encountered, things appear to fall apart quickly and the machine won't even shut down cleanly.
