Found! was Re: [Asterisk-Users] T100P + Capi + Caller ID issue

[Brancaleoni Matteo]

Ok.
enabling zaptel modules debug, I found that when Eicon Diva 
receives a call the T100P slips a lot. 
Idem with another (newer) T100P.

The diva generates 100 irq (more or less) per second, only
when on a call.

Here's the kernel log :

Jun  6 00:19:38 asterisk kernel: New offset: 28
Jun  6 00:19:38 asterisk kernel: New offset: 24
Jun  6 00:19:38 asterisk kernel: New offset: 28
Jun  6 00:19:38 asterisk kernel: New offset: 24
Jun  6 00:19:38 asterisk kernel: New offset: 20
Jun  6 00:19:38 asterisk kernel: New offset: 16
Jun  6 00:19:39 asterisk kernel: New offset: 12
Jun  6 00:19:39 asterisk kernel: New offset: 8
Jun  6 00:19:39 asterisk kernel: New offset: 4
Jun  6 00:19:39 asterisk kernel: New offset: 0

and so on ( continous until the call on the diva server is up ).

What can it be?  any hint about solving that?

the system is rather new, with 512Megs ram.
here are some details :
