As soon as OMSA starts the DRAC stops responding.

This a dell 2950 rev II, with Windows 2008 R2 SP1

Firmware BMC 2.5, Drac 1.65

BIOS is 2.7

I have downgraded from OMSA 7.4, to 7.3, 7.1 and finally 6.5.  Tried racadm racreset racadm racresetcfg, nothing seems to work.  As soon as the OMSA services start, the DRAC stops working.  Rebooting causes DRAC to come alive until OMSA services start again in the OS
