Just a follow-up to the Trixbox and IDE DMA problem. When I loaded the kernel .config settings before configuring the kernel settings, I noticed that the VIA chipset support was already turned ON. I verified this by looking at /boot/.config also. From what I can tell, it seems like a kernel update is required to support newer VIA chipsets on the Core 2 Duo motherboards, which would be fine since I haven't had the chance to do a kernal update before. Should be interesting. Right now I am trying a Trixbox 2 install in case that handles the problem. Not sure if that is going to do anything for us but at least the Sangoma drivers are native to the install.
Comments, suggestions, gotchas?
