Hi,<br>
<br>
I've seen URI driver issues in the past as well. In my situation, all was<br>
working great on an older MoBo. Then, for some new repeaters, I switched<br>
to a latest-generation Zotac Mini-ITX board with AMD 3.2GHz dual-core CPU.<br>
These boxes exhibitied similar green LED issues and "Mr. roboto" like<br>
audio problems. I found the problem was due to a kernel<br>
timer/compatibility bug with the new hardware....A was using the default<br>
ACID install at that point--CentOS 5.3, 2.6.18.xxx kernel.<br>
<br>
I resolved the issue by downloading and "hand cooking" the latest (at that<br>
time--2.6.30.5) kernel which had properly working hi-res timer code. I<br>
also hacked the zaptel-dummy driver to use the hi-res timer. Since these<br>
fixes, both boxes have run perfectly--the latest uptime (which I just<br>
checked) is 208 days. Also, neither box exhibits any cold boot / warm boot<br>
issues.<br>
<br>
