Any use?

Of some. It's failing on ftrace initialization while allocating
memory, but can't know the real reason. It can be just lack of memory
or any other bug.

Probably by that stage of the boot, framebuffer is already loaded. Use
vga=0x317 boot option to get a bigger resolution and more lines on it,
then send another pic.

I hope it fits this time. If not, pick 0x31A, if your monitor allows.

Hi Marcelo

Thanks for the suggestion

I've worked through a decent selection and cant get any to show a higher
resolution than it's currently at, in fact most just leave me with a
blank screen

Note I can change the resolution all I want if I boot via the previous
kernel

Damn :-(
Serial cable then? heh

Cheers,
Marcelo

Yeah I've got a nice little usb one I can hook directly into a raspberry pi on the way

I'm totally expecting this to get fixed in a kernel update before the thing even arrives, but it'll be a good learning experience and will probably be useful in the future!
