Uninstalling ipoib along with disabling/enabling ipoib were recent problems/hangs for ipoib_ndis6_cm.
If you have an opportunity, disable the IPv6 support in all IPoIB (Local Area Connection) instances prior to uninstalling ipoib and see if that helps; it worked as a temp workaround prior to the last set of IPoIB_ndis6_cm patches which fixed the IPoIB disable/enable hang.
