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. )
It looks like your development box is having problems with
interrupts from the card. Once you run dahdi_cfg for the span you
should be getting 10000 interrupts/sec and above I can see you only
got 28.
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
Do your development boxes work with an older version of DAHDI? Just
not 2.3.0.1? Also, why not upgrade to 2.5.0.2 or the trunk of the
2.6 branch?
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

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
