2.5.67-mm1 cause framebuffer crash at bootup

[As this one is matroxfb only, I removed others...]

It should not happen. Did not you get some rejects while patching?

If your kernel binary is simillar to mine, it looks like that fbops->fb_imageblit was NULL. It should not happen, as matroxfb's fb_imageblit should point either to no_imageblit (which currenlty does nothing, but it should complain loudly) or to cfb_imageblit (which paints character) or matroxfb_imageblit (which should paint character too).

But from call trace it looks like that some printk() error got triggered on your config. Can you try booting with serial console? Do you see penguins on the screen, or not?

Or remove body from drivers/video/console/fbcon.c:check_vc() - it should is not triggered on Linus kernels, but maybe -mm1 moved something around. It looks like that it is time to download -mm1 :-(
Thanks,

No penguins on screen.
I don't see any problems logged. I did boot with serial console. It's attached.

Actually this is just 2.5.67 + mga-2.5.66-bk12 with and without my earlier-keyboard-init.patch...
