Watching the console for a while I see regular messages, which I could
also find in /var/log/messages:
Dec  3 16:37:15 asterisk1 kernel: zaphfc[0]: received d channel frame with
bad CRC.
Dec  3 16:37:36 asterisk1 kernel: zaphfc[0]: empty HDLC frame received.
Dec  3 16:37:36 asterisk1 kernel: zaphfc[0]: received d channel frame with
bad CRC.

Can anyone with one or more HFC-PCI card(s) (esp. in The Netherlands)
check if they see these on a regular basis as well? (And I am talking many
times an hour here!)

TIA!
