Hi,

I compile a new kernel with the video support, flash the gumstix and at the first reboot I've got the following message:

<0>Kernel panic - not syncing: Attempted to kill init!

Is this a PXAFB problem, because I read a similar post in the mailing list, but the only answer I read is "enable the PXAFB support (if I'm remind correctly). But were can I do that ?

Any clues,

thanks,

Antoine
