font-family:Garamond'>I am using an E100P with all the latest asterisk and
zaptel versions (0.9.1). I carefully ensured that my E100P wasn’t sharing
interrupts with any other devices in my system. Problem is that I get the occasional
crackle during phone conversations. Looking deeper the crackles are always
associated with IRQ misses which seem to occur when data is being read/written
to the disk. Crackles always occur when the disk active LED on my PC is
blinking. Running patlooptest (with a loopback adapter fitted to the card) shows
essentially the same thing ie) data errors at times when my disk is active. It occurred
to me that the fault may lie as much with the disk drivers as with the E100P. If
they were disabling interrupts for “lengthy” periods then it wouldn’t
be surprising that the E100P was not able to service its interrupts in a timely
manner. My system is fitted with a standard IDE disk. If anyone has a system
that works without crackles and IRQ misses please could you let me know what type
of disks you are using.<i><span style='font-style:italic'><o:p></o:p></span></i></span></font></p>
