[RTnet-developers] removing rtipv4

[Dietrich P. <dpe...@mi...>]

Dear All,

after using rtnet whenever I try to remove the rtipv4 module
I get
ERROR: Removing 'rtipv4': Device or resource busy
allthough from lsmod rtipv4 seems not to be used...

this is my lsmod  output

rt_loopback             2308  0
rt_e1000               88512  0
rtpacket                5216  0
rtipv4                 25080  0
rtnet                  30176  4 rt_loopback,rt_e1000,rtpacket,rtipv4
rtai_rtdm              44228  4 rt_e1000,rtpacket,rtipv4,rtnet

I have to reboot in order to be able to remove the modules, which is not very 
comfortable.
I m using rtnet-0.9.11

Thanks in advance for any suggestion.

Are you trying a manual remove (rmmod / modprobe -r), or is this
messages generated while running the rtnet script? Does repeating 'rmmod
rtipv4' at the stage printed above give you that message?
