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.
