Description of problem: I have Fedora 15. Originally everything worked fine. But some time ago there must have been some update that broken the reboot/poweroff capability for me. Every time I try to reboot, the system just hangs. When I use sysrq to send sigterm to all processes, I see a message on system console (not literal): [lvm] there are still devices being monitored [lvm] refusing to quit I have to kill all processes using sysrq to reboot successfully. This happens always. How I can produce some debug logs to help you fix this issue? Version-Release number of selected component (if applicable): lvm2-2.02.84-3.fc15.x86_64 How reproducible: always
See bug #681582 I think there is test package mentioned there which should help. *** This bug has been marked as a duplicate of bug 681582 ***
