Thanks David,
I will investigate the timer res and get back to you....

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