[Asterisk-Dev] Odd problem with asterisk in boot time (Second part and answer)

Dear Developers:

I fund the solution of the problem, ist no to easy to identifacte but 
what happen is this:

I modify the /etc/init.d/zaptel file, replacing the "insmod" and "rmmod" 
with the "modprobe" equivalentes commands, The old form to load an 
unload modules in FC2 with Kernel 2.6.7 don't work well.

And if you have "Kudzu" (The hardware discovery service), in the test of 
the TDM400P, left the PCI Channel of the TDM card bloqued and the Zaptel 
scritps don't load correctly the modules for the hardware, then the 
asterisk send the following message and few seconds later die:

chan_zap.c:765 zt_open: Unable to specify channel 2: No such device or 
Jul 28 20:28:07 ERROR[1073880224]: chan_zap.c:5879 mkintf: Unable to 
open channel 2: No such device or address
here = 0, tmp->channel = 2, channel = 2
Jul 28 20:28:07 ERROR[1073880224]: chan_zap.c:8721 setup_zap: Unable to 
register channel '2'
Jul 28 20:28:07 WARNING[1073880224]: loader.c:328 ast_load_resource: 
chan_zap.so: load_module failed, returning -1
Jul 28 20:28:07 WARNING[1073880224]: loader.c:423 load_modules: Loading 
module chan_zap.so failed!

I reboot the hardware 20 times and when deactivate the kudzu service 
(for fast boot), everything go ok.

I think is necesary check how the Zaptel modules as load.

A easy workaround is deactivate de Kudzu service and modify the zaptel 
initialization script with modprobe.

And i think (in personal form), we need more efforts in Kernel 2.6 
development and forget Kernel 2.4

Best Regards.... Fernando Romo
