You could help us by installing a debug version of 28.0 release on some of your servers (either use mysqld-debug binary in release RPMs, either DEBs at http://www.percona.com/downloads/TESTING/5.5-debug/), installing gdb, and sending us crash messages if it crashes or gdb stacktraces if it deadlocks. For stacktraces, run gdb -ex "set pagination 0" -ex "thread apply all bt" --batch -p $(pidof mysqld) at the time of deadlock. Thank you!
