I've bought 3 licenses from Linuxant for HSF modems and all have the
same problem. The connection lasts seldom longer than 10-15 minutes.
Even when running a ping in background, as suggested in the FAQ.

Debugging information follows.

Thanks for any help,



uname -r:



In my syslog:

localhost kernel: Conexant: RX FIFO OVERRUN (Bus Latency) - FIFOE<3>
