  [Impact]

   * Percona will segfault when exposed to medium load, almost imediately
   * This is because of a bug in upstream, which manifests on ARM and PPC

  [Test Case]

   * Install and configure percona-xtradb-cluster-server
    * Run sysbench against configured node (only one node is needed, no need 
for proper cluster):
     # sysbench --test=oltp --oltp-test-mode=complex --max-time=60 
--num-threads=110 run
   * mysqld will segfault seconds withing starting the test

  [Regression Potential]

   * This is a cherry-pick from an upstream fix 
(https://jira.mariadb.org/browse/MDEV-6450)
   * This is not fixed in upstream Percona becasue Percona does not officially 
support non-intel archs.
   * Because code adds additional memory barriers there was a chance of 
performance degradation on i386/amd64. However, intensive sysbench syntetic 
loads proved this is not the case - there are no performance penalties.

  [Original 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 100;
  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 7038321152 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.

Bug description:
  [Impact]

   * Percona will segfault when exposed to medium load, almost imediately
   * This is because of a bug in upstream, which manifests only on PPC

  [Test Case]

   * Install and configure percona-xtradb-cluster-server
    * Run sysbench against configured node (only one node is needed, no need 
for proper cluster):
     # sysbench --test=oltp --oltp-test-mode=complex --max-time=60 
--num-threads=110 run
   * mysqld will segfault seconds withing starting the test

  [Regression Potential]

   * This is a cherry-pick from an upstream fix 
(https://jira.mariadb.org/browse/MDEV-6450)
   * This is not fixed in upstream Percona becasue Percona does not officially 
support non-intel archs.
   * Because code adds additional memory barriers there was a chance of 
performance degradation on i386/amd64. However, intensive sysbench syntetic 
loads proved this is not the case - there are no performance penalties.

  [Original 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 100;
  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 7038321152 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.
