No, and the discussion seems to have stalled. The original author of
the commit said that he was able to reproduce it when snapshotting a non
root lv, but only if there was some io activity going on at the time of
the snapshot. He got a sysrq-w output showing the lvcreate process and
a kernel mode thread stuck with their stack traces, but no idea what the
actual problem is.
