Hi guys,

I just wanted to say that there's another user that have reported
success with the JMC250 (different card) using the jme driver with the
fix.

He was also getting hangs apparently.

I got an email from him, see his response here: http://ix.io/oBA

It's the same user that have posted this:

Thanks,
Diego
