[App_rpt-users] URI frustration

[David McGough]

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.
