I've just had a look at this.  Seems to be a problem related to
the kernel trying to invoke non-existant usermode helper progs.

I created a script /sbin/hotplug containing just


#!/bin/sh
echo hotplug: $* > /dev/console


and my kernel no longer crashes when trying to establish an async
ppp link.  Instead, I get this in syslog:

Mar 20 16:24:33 merlin pppd[221]: Serial connection established.
Mar 20 16:24:34 merlin insmod: Note: /etc/modules.conf is more recent than /lib/modules/2.4.9-32/modules.dep
Mar 20 16:24:34 merlin pppd[221]: using channel 1
Mar 20 16:24:34 merlin pppd[221]: Using interface ppp0
Mar 20 16:24:34 merlin pppd[221]: Connect: ppp0 <--> /dev/ttyS1

Mar 20 16:24:35 merlin pppd[221]: read: Resource temporarily unavailable
Mar 20 16:24:35 merlin pppd[221]: read /dev/ppp: Resource temporarily unavailable
Mar 20 16:24:36 merlin pppd[221]: rcvd [LCP ConfAck id=0x1 <asyncmap 0x0> <magic 0x7837ff6f> <pcomp> <accomp>]
Mar 20 16:24:38 merlin pppd[221]: sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0x7837ff6f> <pcomp> <accomp>]
etc
etc

I guess next I need to figure out what is causing the "Resource
temporarily unavailable" (assuming that is an error).

iirc we have had problems with non-existant usermode helpers before,
and had to turn module support off until we had modutils ported.
