Description Christopher Scott Kindley 1999-02-17 15:25:20 UTC

Using duel channel bonding on external ISDN modems not
possible with this version shipped with RedHat 5.2.
Downgrading to ppp-2.2.0f-5 from the 5.0 distribution allows
normal use of both b channels bonded. Only errors listed in
/var/logs/message was a connect script error. However
WITHOUT modifying anything and just downgrading to
ppp-2.2.0f-5 only this error disappeared. Below is the error
given.

we are very interested in knowing whether ppp 2.3.6, which is
available in the RawHide Tree and/or Red Hat Linux 5.9 beta, has fixed
your problem.  We don't have access to ISDN in the test lab so we
cannot verify that the problem still exists.  If you could get the
SRPM from RawHide and build it on your system, and test whether or not
the problem has been corrected, we would greatly appreciate it.

fix is to put asyncmap 0 in the options file.
