Comment 1 John Horne 2005-10-01 23:22:09 UTC
This also occurs under i686 (32-bit) hardware.


Comment 2 John Horne 2005-10-01 23:41:22 UTC
As far as I can tell the change between the kernel-2.6.12-1.1456_FC4 and
kernel-2.6.13-1.1526_FC4 kernel releases causing the problem could well be this:

  commit cd987d38cc59053e0bab8150ffaca33b109067f3
  Author: gregkh@suse.de <gregkh@suse.de>
  Date:   Wed Mar 23 11:12:38 2005 -0800

      [PATCH] class: remove class_simple code, as no one in the tree is using it 

      Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This was taken from the 2.6.13 kernel changelog.


Comment 3 Dave Jones 2005-10-02 23:11:37 UTC
works fine here.

(19:13:25:root@firewall:~)# uname -a
Linux firewall.kernelslacker.org 2.6.13-1.1526_FC4 #1 Wed Sep 28 19:15:10 EDT
2005 i686 i686 i386 GNU/Linux
(19:13:45:root@firewall:~)# modprobe ppp_generic
(19:13:51:root@firewall:~)# dmesg | tail -n1
PPP generic driver version 2.4.2

A grep across the kernel source doesn't show any instance of those symbols.

Are you guys building your own ppp_generic module from source ?

Comment 4 Thomas Antony 2005-10-03 04:18:51 UTC
It is a bug in the kernel_ppp_mppe package
I have installed dkms-2.0.6-3.fc4 from Fedora Extras and
kernel_ppp_mppe-0.0.5-2dkms from pptpclient.sf.net.
