Good morning everyone!
I have the same problem with a new install 2.6.1+ & 2.6.1 and I get the same InnoDB errors at Mysql LOG and hangs in the install database script .
My sever is a Centos 6.5 64bits + php 5.3.24 + MySQL 5.5.34. This server have other installations of Moodle campus without problems, one of these is a 2.6.0 upgraded to 2.6.1+ without any problem.
I use Virtualmin to create domains/database automated, so I discard any problem with user privileges.
Regards!
Tx
