[Asterisk-Users] Re: [Asterisk-Dev] X101P register map data please?

Hi Newbie, or would you prefer to be called VoIP(y)? :-)

Thanks for the advice, It's great to hear from somebody that has 
suffered in the same way :-)

I've cc'd in the dev and user lists mostly so that others looking for 
the same issue (FXO PCI Master Abort) can find some info! - hope you 
dont mind...


On the card itself.
	I am assured by the vendor that they had the card up and running in a 
machine. Indeed, the vendor has taken one home, called me through it, 
and then given it to me... so I'm reasonably sure that under SOME 
situations, these cards work.... and I now have 2 of these cards!

I'd be interested to know, are all the 3 cards you have had "identical" 
in terms of how they look? Do you still have them? Can we compare notes 
- (off list)?

On the Zaptel driver...
	There are clearly inconsistencies in the driver, which I feel should 
be sorted out.... However, they are in code which people with working 
systems say is never reached. So.. yes, the driver should be cleaned up 
in order to handle the IRQ's better, but the question remains, why am 
I/you getting the Master Aborts in the first place...

If the patch that I've done to the driver is the right thing to do, 
then maybe thats an answer for me/you/others. I still seem to have some 
problems, so I need to understand those first (see other post). At 
least the Master Abort doesn't bring the whole machine down.

What I can't tell is why WE get the Master Aborts in the first place....
Speculation would be good! Any ideas?

Cheers

Mark.
