Disable AIM/VPN-EP module - Solution for VPN

Hi, in Cisco Bugtool, there are some bugs related with module AIM/VPN-EP module.

We have a 3640 router, and I has been some problems.

The vpn works in the most of time, but, in a few moments, the communication stops, and a communication fails, and suddenly the connection works.

The related bug that I found is CSCdz61466, and there are others bugs related with this, that say to disable hardware encryption.

I would like to know, which way to disable this module.

There are some command for this , or only way is desinstaling the moduling.?

Anyone have a idea about this?

the tunnel vpn is closed by a router 3640 and a 1720 with ios c3640-jk9s-mz.122-8.T5.bin in both sides.

I verified many times the configuration of routers and make a troubleshooting with them, and i have sure every is allright.

I think you can shutdown all the interfaces on the AIM/VPN-EP module to disable it. Ofcourse, deinstalling it physically is also one of the ways of disabling it.
