I now think it _is_ probably hardware, although I've got ISDN I use an
external TA so an RS232 connection is involved (and RS232 is almost
inherantly unreliable :-( )

I did think of checking that - I'm not seeing ppp checksum errors but...

Yes I get it very consistently and using an older kernel does make it
"go away" but only because 2.0.36 doesn't bother reporting them!
If I patch the kernel to include a bad checksum error message I see
them in 2.0.36 as well
I'll do a bit more digging but I think that it's probably hardware -
time to buy an ISDN card methinks (although where I'll find an IRQ for
it...)
