>Description:
I have a Zoom model 2920 pci modem on sio1 and connect to my ISP with user ppp. I keep getting this message on the FBSD console 'xx more sio1 interrupt-level buffer overflows'. Had this same problem with a USR pci modem that I exchanged for this zoom modem. I also get this message when I use 'tip or cu' command to issue the hayes AT command ATI11 to the modem to display the last connection values.



>How-To-Repeat:
Install a Zoom model 2920 pci modem and use tip com2 command to get connected to modem hardware, enter ati11 to display the last connection values. This always makes the sio1 interrupt-level buffer overflows message happen.
>Fix:
  I think the sio handler module needs to be looked at. One other poster to the questions list said he got the same message after he upgraded from 3.3 to 4.4.
