Hi.

I was trying to use the remote control and I got the following error
in the kernel.
I remember I used the Remote Control 4-5 months ago with success.
To reproduce the problem it is enough to send a key with the remote to the card.

Fedora Core 5
kernel from source 2.6.18
latest (1 hour ago) mercurial of v4l-dvb

Loading the card

and then when a key in the remote is pressed

It happened more that once (with and without X)
Afterward the system is hardly able to reboot.

Any more debug I can provide?

Thanks

Mario
