[Asterisk-Users] IRQ Problems

[Tom Hayden]

Hello
I just installed a TE110P in a Dell Poweredge 750 (rackmount), which
is connected via crossover T1 cable to a adit 600.  Anyway, I've
encountered an array of errors, which I believe I have narrowed down
to the 22 IRQ misses I encounter on zttool. I've noticed that the
te110p and the usb device share an IRQ. Could that be the source of my
woes? Would disabling the usb device in the bios solve my problems or
could it be my configuration?
