Ubuntu has this issue in their open bugs list:

https://bugs.launchpad.net/ubuntu/+source/linux-ubuntu-modules-2.6.24/+bug/220857

It is not an issue of the old video-buf being used -- I don't have the
old module present on my system at all:

/lib/modules/2.6.24-16-generic/kernel/drivers/media/video/videobuf-vmalloc.ko
/lib/modules/2.6.24-16-generic/kernel/drivers/media/video/videobuf-dma-sg.ko
/lib/modules/2.6.24-16-generic/kernel/drivers/media/video/videobuf-dvb.ko
/lib/modules/2.6.24-16-generic/kernel/drivers/media/video/videobuf-core.ko

Tim Gardener says to use the linux-headers-lum-`uname -r` package
rather than linux-headers-`uname -r` , but that is not working,
either.

Hopefully this will be resolved soon -- Hardy Heron has already been
released, containing this bug!

Regards,

Mike
