Every so often (usually once a day) I lose connection from my ISP. I'm sure this is initiated from the ISP. I use a script to reboot* when pings fail. Thsi overcomes the immediate problem, but there is something going on that I don't understand, and I think is a bug. (perhaps in a driver?)

Can anyone shed some light on what line 3 from my logs may indicate?
This is what my PPP log shows before one of the failure:
Line Log entry
1 09:11:20 pppoe Session terminated -- received PADT from peer
2 09:11:20 pppd LCP terminated by peer
3 09:11:21 pppd ioctl(PPPIOCSASYNCMAP): Inappropriate ioctl for device(25)
4 09:11:21 pppd tcflush failed: Input/output error
5 09:11:21 pppd Exit.

I am really unsure as to where to look. I've googled for ioctl and found a great definition, but it doesn't seem to say anything about the particular error I'm getting. Googling for this error shows a whole bunch of people with the same question - and no apprarent answer!

Thanks
