Description Pekka Pietikäinen 2004-08-27 17:53:42 UTC

Description of problem:

This could actually be initscripts, ppp, udev, mkinitrd or dev, but
filing it under initscripts since that's what gets stuck.

mkinitrd-4.1.6-1
udev-030-7
package dev is not installed (yum upgrade failed since it thought /dev
was devfs and nuked it!)
initscripts-7.71-1
ppp-2.4.2-4

[root@the RPMS]# more /etc/sysconfig/network-scripts/ifcfg-Baana
...
ONBOOT=yes
DEVICE=ppp0
PROVIDER=Baana
LINUX_PLUGIN=rp-pppoe.so

like this when networking is started, the system just gets stuck
there, the alt-sysrq keys don't report anything useful etc.
ONBOOT=no and ifuping it in rc.local works but it has
to try it a few times:

Aug 26 19:30:18 the kernel: CSLIP: code copyright 1989 Regents of the
University of California

Aug 26 19:30:23 the pppd[3603]: PPP session is 47388

Problem could be a missing /dev/ppp. syslog isn't up at that point
so debugging is a bit nasty. Could change the ordering I suppose...

Comment 1 Pekka Pietikäinen 2004-08-27 18:05:20 UTC

Blah... recreating the mkinitrd or something todays rawhide actually
fixed this problem. The dev-getting-nuked is a bug I suppose, but
things work just fine without it so... :-)

Comment 2 Pekka Pietikäinen 2004-09-04 09:34:37 UTC

Bug is back, moving syslog before networking shows the 
system goes into a (this from the old log but the messages are the
same :-) )

Aug 26 19:30:18 the pppd[3592]: Plugin rp-pppoe.so loaded.
Aug 26 19:30:18 the pppd[3592]: Linux kernel does not support PPPoE --
are you running 2.4.x?
Aug 26 19:30:18 the pppd[3592]: Exit.
Aug 26 19:30:18 the adsl-connect: ADSL connection lost; attempting
re-connection.

loop, after all initscripts have run udev seems to notice it should be
creating /dev/ppp and what happens is like in the log above,  I'm
still not sure what conditions are required for that to happen though.

initscripts-7.77-1
udev-030-20
ppp-2.4.2-4
mkinitrd-4.1.9-1
dev-3.11-1

Not sure which component should be responsible for creating it,
/sbin/kmodule & rc.sysinit from initscripts or udev_start/startudev 
from udev?

Comment 3 Bill Nottingham 2004-09-06 20:53:55 UTC

udev, AFAIK.
