Binary package hint: linux-image-2.6.27-7-generic

My Nova T 500 card works well in Hardy with kernel 2.6.24-22-386 and earlier.
It fails utterly in Intrepid Ibex Ubuntu 8.10 with kernel 2.6.27-7-generic

The first problem is that the firmware always fails to load first time.

[ 26.368380] usbcore: registered new interface driver dvb_usb_dib0700

The number the firmware download fails at changes, but the "with -110" is always the same.

I've installed the same recent drivers and firmware from http://linuxtv.org/hg/v4l-dvb
over both the 2.6.24 and 2.6.27 kernels. This problem remains the same.

This make me think the unwanted feature is closer to usb-core that it is to the dvb-usb-dib0700.

The problem also still exists in linux-image-2.6.27-9-generic.

If I remove the modules and then modprobe dvb-usb-dib0700 the firmware always loads.
