After upgrading to 2.2.1 (from 2.0.32), the PPP connection stopped
working. All necessary software has been upgraded with the kernel (the
system itself is RH5.2 based). Login and PAP authentication apparently
succeed, but nothing goes through. The "bad frame" errors (see log) keep
coming about every 30 seconds; pinging any host also causes a bad frame
message.
The modem is actually a ZyXel external ISDN connected via ttyS2 with
high-speed serial card - in essence acting as a very high speed modem.
Everything was, thus, working perfectly under the old kernel & pppd.
Any help would be greatly appreciated.
