Re: [proaudio] FATAL: Error inserting realtime module

["independent commercial" <independentcommercial@xxxxxxxxx>]

If I'm right this was covered recently before because I had the same problem. Realtime module conflicts with commoncap and possibly capability too. Don't load them and see if realtime loads.

I found the problem with this, I loaded realtime module first and so
commoncap wouldn't load. I unloaded realtime

# rmmod realtime

and the loaded commoncap

# modprobe commoncap

and commoncap loaded. Unfortunately, I'm back to where I started, I can'
t load realtime module, I rcv the same error as above.

This makes me think of two possible problems: the order of loading the
modules are incorrect or commoncap and realtime are mutually exclusive.

Any thoughts?
