Bug description:
  I'm trying to set up percona-xtradb-cluster-5.5 on PPC machine. While
  the package installs fine, as soon as I run sysbench oltp becnhmark
  against it, Percona dies (even when I start the benchmark with just
  one connection).

  I can also crash mysql manually, by updating the sbtest table (which
  is created by the sysbench utility):

  mysql> update sbtest set pad = 'mario1' limit 1000000;
  ERROR 2013 (HY000): Lost connection to MySQL server during query

  Sometimes I need to repeat this update (with different values for
  'pad' field) few times. This happens regardless of whether I run the
  UPDATE inside the transaction or not.

  This is the assertion found in the log file:

  170117 21:10:55  InnoDB: Assertion failure in thread 70366668321152 in file buf0buf.ic line 1277
  InnoDB: Failing assertion: block->page.buf_fix_count > 0

  This is a single-node percona-xtradb-cluster server, without
  wsrep_provied configured, run inside 14.04 lxc container on 16.04
  host.

  I'm attaching the full log file, mysql configuration file and the core
  dumped.

  The version of the package installed is this 5.5.37-25.10+dfsg-
  0ubuntu0.14.04.2.
