[Asterisk-Users] te410p with serial console fails with error: TE410P: Double/missed interrupt detected

te410p with serial console fails with error: TE410P: Double/missed
interrupt detected

I am having trouble getting the te410p to work with a serial console.  Has
anyone else had this problem?  Am I doing somthing wrong? Interupt
problem? Is this a bug?

after modprobe wct4xxp, I get the following message loop on console untill
I modprobe -r wct4xxp.

TE410P: Double/missed interrupt detected
TE410P: Double/missed interrupt detected
TE410P: Double/missed interrupt detected


On redhat 9 without serial console, it works but with errors.

working grub line:
kernel /vmlinuz-2.4.20-20.9smp ro root=LABEL=/ hdc=ide-scsi
