[linux-dvb] crash with terratec cinergy hybrid XS [0ccd:0042]

Hi,


The mailman on mcentral.de seems to be dead, so I'll ask here.


I installed userspace-drivers and em28xx-userspace2 with a  2.6.24.4
kernel with mactel-linux patches(some macbook specific drivers).

I needed to activate some dvb-support to get the drivers compile
cleanly, e.g. v4l1-compat, IIRC.

When I plug in the device, em28xx.ko is loaded and the usb subsystem
kind of crashes. Internal and external keyboards(both attached via USB)
do not work anymore, but mouse+touchpad works. When media-daemon is
enabled, I get this with dmesg(USB freezes without media-daemon, too):

The segfault is probably not intended.
Last time I looked, I have no /dev/dvb/* in this state.
Removing the device doesn't get the keyboard back.



any help appreciated,
