I have the same issue with IBM 2005-H16 "v5.3.2c" attached to 2498-B24 "v6.2.0e" , when we upgraded the 2498-B24 to "v6.3.x" the E-Port changed to G_port suddenly and many trials have been made to fix that without success.
Then we tried updating to v6.4.0a as a trial to fix this issue, but no change happenned, anyone can help?

Oddly enough we have experienced this on a Brocade 5300 after upgrading to Firmware Version 6.4.2a. The only way to fix the "G" port problem on ISLs was to reboot the core (5300) switch. After reboot everything worked fine.
If you are having problems with unexpected G ports after a firmware upgrade, rebooting might be your best option. Just make sure you have dual paths or you have issues.
