Which distro are you using?Ubuntu 11.04 64-bit but with vanilla 3.0.3 kernel Ubuntu's lvm: # lvm version LVM version: 2.02.66(2) (2010-05-20) Library version: 1.02.48 (2010-05-20)So I'd guess you might be a 'victim' of Debian home-brew udev rules for lvm2, which were unfortunately not consulted with upstream (nor udev, nor lvm).
Indeed I have had a few bad experiences with Ubuntu's udev rules, but never like this... I don't think a wrong udev rule can hangup the whole machine with such symptoms, you really think so?
- lvs and/or "lvchange --refresh ..." processes hanging forever in kernel code (and AFAIR it was in DM region, that's the /proc/pid/stack trace which I unfortunately lost)
- "sync" also cannot complete, so I can only do force reboot without flush
