Anyway you need to compile all drivers from the same tree else things
will go wrong.


thank you for your answer. As you can see in the logs of my first
message I tried "make rmmod" in the v4l-dvb directory. This has the same
effect as "make unload". The script is not able to unload the drivers
(ERROR: Module .. is in use).

Any other ideas how to unload the drivers?

Easiest way to rmmod stb0899 is to go to your v4l-dvb devel directory 
and do;
sudo make unload
indeed stb0899 is needed by other drivers (like budget_ci and others). 
So this command will remove them all.
Anyway you need to compile all drivers from the same tree else things 
will go wrong.

cannot rmmod stb0899

[Andreas Besse]

Hello,

I'm using a KNC One TV-Station DVB-S2 Plus and a WinTV-NOVA-CI PCI with
the multiprotocol drivers from http://www.jusst.de/hg/multiproto/
(changeset: 7218:2a911b8f9910, date: Wed Jul 09 23:07:29 2008 +0400)

The drivers run fine since 250 (!) days, but I have an issue with high
cpu load. So I decited to apply the patch "Fix High CPU load in 'top'
due to budget_av slot polling" from Oliver Endriss or try the current
v4l tree.

First i tried to remove the current drivers. If i call "rmmod stb0899"
the driver is not removed. Instead an Error "ERROR: Module stb0899 is in
use" is shown (but no application is using the device)

I also tried "rmmod -w stb0899". This leads to an infinite loop and I'm
not able to kill the process.

How can I rmmod the stb0899 driver without rebooting the system?

How can I kill "rmmod -w stb0899"?

regards,
Andreas Besse
