Hi all,
I have a particular install of a tdm400p (REV E/F) in which 'top'
reports the irq CPU state is constantly >50%. ie:
CPU states: cpu user nice system irq softirq iowait idle
total 0.7% 0.0% 0.5% 50.4% 0.0% 0.0% 48.1%
The above is _without_ Asterisk running. The heavy irq usage will cease
the moment I rmmod wcfxs.
The card has 2 fxo and 2 fxs ports. However, even if I comment out all
the channels in zaptel.conf & run ztcfg (ie: 0 channels configured), and
then reinsert wcfxs ... the irq CPU state still jumps to >50%.
I suspect that either the digium card is bad, or my motherboard is to
blame (Asus A7N8X). Does this behaviour sound familiar to anyone?
Thanks in advance,
Ryan
