[asterisk-ss7] Sangoma A108 - problem while using all 8 ports, but normal with up to 7 ports.

Hello!

Just interested, if anyone have/had a similar problem with 
Sangoma A108 card. When I use ALL 8 ports on it - I loose 
signalling on all plugged ports (chan_ss7) - if I use up to 
7 ports - it's OK. Use of TDM ports - regardles of 
signalling - it could be PRI or SS7 - I do plug 8th port 
and voila, signalling on all ports is lost, all ports shows 
on the "ss7 link status" - Proving, Down but not coming to 
IN SERVICE, when I unplug - I mediatelly getting my 
sigchans back. 

looks like hardware problem with internal card's cpu power 
or something like that, so it does not reliably transfer 
all of the timeslots to the asterisk. I did not notice that 
before, since I have a several cards in single system, and 
did not used all of the ports on any single A108 card in 
the system before.
