[asterisk-users] TE410P (1st) without cables always green

[Marcio Gomes]

Hello Shaun,

Thanks for your answer, I try all dahdi I can compile in Slackware 13.1 and 13.37 ( recently I downgrade to 13.1, to compile some
older kernels,  but it is not the answer. )

Yeah.. I forget to look at it.  As i say, I try with all.. let's go.. I recompile the
dahdi-linux-complete-2.6.0+2.6.0 witj  2.6.33.4 kernel. The interrupt problems persists.

   20:        630       1476   IO-APIC-fasteoi   wct4xxp

All versions 2.2.XXX to SVN same problems...

This is interrupt outputs to today SVN :

   20:       1348       1788   IO-APIC-fasteoi   wct4xxp

* this is the NEW setup , the system has 2 hardisks with 2 slacks, 2 asterisk setups.. all compiled from sources ( I not like
pre build softwares , when i am in trouble I have serious problems to modify, and slackware has poor packages but is lovely
stable distrib )

I really not understand de APIC changes in IO-APIC-XXXX  and the greater 100 Interrupt numbers in old setups.. can you help me ?
