Alright, is the particular failure mode useful/interesting/detectable?
Presumably packets arrive at the remote end and fail CRC checks [let's
see a packet trace]?

Perhaps a solution is to have pppd attempt to detect this particular
sort of failure at startup time and proactively disable rfc1323, or at
least loudly suggest the user do so?
