Hi Hans, Thank you
I'm not going to upgrade the kernel alone as this will cause a lot of problems with the updates from SUSE. I was planning to upgrade to SUSE 10.1 (which should have kernel 2.6.15) in the nearer future anyway, so I'll try to perform the upgrade as soon as possible and let you know the result. Again thanks for your effort. Hans Verkuil wrote: > Hi Martin, > > Please apply the attached patch to the ivtv-queue.c source.
