I am having the same problem, here are some variables if that helps :

mysql> show global variables like 'ver%';
+-------------------------+---------------------+
| Variable_name | Value |
+-------------------------+---------------------+
| version | 5.5.32-log |
| version_comment | Source distribution |
| version_compile_machine | x86_64 |
| version_compile_os | Linux |
+-------------------------+---------------------+
4 rows in set (0.00 sec)

mysql> show global variables like 'innodb_buffer%';
+---------------------------------------+-------------+

6 rows in set (0.00 sec)

mysql> show global variables like '%adaptive_hash_index%';
