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
