Attempting to snapshot the root lv causes a deadlock in 2.6.35 when it suspends the root lv device to replace the table. The lvcreate -n snap -s -L 1g lv/root command hangs, can not be killed, and no further IO is possible, and the system must be hard booted with magic-sysrq.
Started with Ubuntu 2.6.35-rc3-3 kernel, then tested mainline kernels 2.6.35 rc1, rc2, and rc3 all have the issue. Mainline 2.6.34 does not have the problem. Hopefully I'll be able to do some git bisecting tonight.
