please report bug then, with system configuration (lvmdump)
and process backtrace (log from echo t>/proc/sysrq-trigger)
when it deadlocks.

pvmove should work for moving root volume
(except some special situations, like when you increase log level
and log itself is on moved LV)

(And I used pvmove several times myself to move system disk to another
without any problems on RHEL5.3)
