Re: [Asterisk-Users] Unpredictables Hangups
Michael, I just check'd my kernel configuration... I have APIC support and no Enhanced Real Time Clock, exactly as you have on your hardware. It *could* be a timer issue, except that i can't manage how to "accelerate" mi timer or to slow down my t1xxp driver... -- Stefano -- Outgoing mail is certified Virus Free.

Hi again Stefano, I noticed your E100P card generates 10 times as many interupts as your timer - don't know if that could be the issue.
