Distribution: opensuse 10.3

Hardware Environment: vmware

Software Environment:  opensuse 10.3, vanilla 2.6.26-rc1

Problem Description: 
you may experience issues after loading/unloading l440gx module

see 
"[BUG] crash - modules l440gx and parport_pc interfere" ( http://marc.info/?l=linux-kernel&m=119921813509606&w=2, http://marc.info/?l=linux-kernel&m=119922045311664&w=2 )

Steps to reproduce:
modprobe l440gx;modprobe -r l440gx (no need for having appropriate hardware attached)

Comment 1 Roland Kletzing 2008-10-26 14:52:11 UTC

on 2.6.27, modprobe l440gx prints this message (it didn`t do that before):

If this is still seen with a modern kernel please update
