create table demo (info string);
insert into demo (info) values ('test 1 [DEM]');
flush ramchunk demo;
alter table demo modify column info text;

without 'flush ramchunk' example above produces also impossible combo of flags:

mysql> alter table demo modify column info text;
Query OK, 0 rows affected (0,01 sec)
