It is good to know 6.1 works and 6.2 doesn't for you.  But I'm not
understanding why you're thinking it is a device-mapper-multipath
issue (not kernel issue).

You could do a couple things:
1) run the RHEL6.2 kernel on a RHEL6.1 install
2) install RHEL6.1 device-mapper-multipath package on RHEL6.2 install

If both work then it implicates the RHEL6.2 device-mapper-multipath
package.

But all being said, please just file a BZ at bugzilla.redhat.com
