To help identify hangs, MDEV-33053 introduced an InnoDB warning message. This warning is occasionally being issued during the execution of a number tests. So far, the following tests have been observed failing due to this added warning:
encryption.innodb_encrypt_temporary_tables
|
galera.galera_gcache_recover_full_gcache
|
innodb_fts.innodb_fts_misc_1
|
innodb.ibuf_delete
|
innodb.innodb-64k-crash
|
innodb.innodb_stats_external_pages
|
innodb.innodb-wl5522-debug
|
innodb.purge_secondary
|
Here is an example:
|
bb-11.2-release fccc1fa3f5e0fed4033a0bb46155e60220a3ba1
|
galera.galera_gcache_recover_full_gcache 'innodb' w1 [ fail ] Found warnings/errors in server log file!

I think that we simply need to add a global suppression for this warning:
