Subject2.6.0-test3 oops in cfb_imgblt
This oops happens within a few seconds of starting up a 2.6.0-test3
kernel using statically linked framebuffer console code. Seemingly
the killer is when the output gets near the last line of the screen.
It happens consistently, making this unusable ... but for the few
moments before it oopses, I finally get a full screen text console!

It's elderly hardware that's been pretty happy with Linux from day one,
although this is the first time I've gotten the 2.6 console FB code to
work even this well with it -- so in that sense this is progress, though
it's a regression from 2.4 kernels. (Where I didn't use FB_NEOMAGIC; but
then, FB_VESA never yet worked on 2.6 when I tried it, so I didn't even
try it this time.) When the FB kicks in, dmesg reports this:

neofb: mapped io at c5000000
Autodetected internal display
Panel is a 800x600 color TFT display
neofb: mapped framebuffer at c5201000
neofb v0.4.1: 2048kB VRAM, using 800x600, 37.878kHz, 60Hz
fb0: MagicGraph 128XD frame buffer device
Console: switching to colour frame buffer device 100x37

At that point the logo finally shows up and then most of the screen (below
the penguin) turns white; the white scrolls of as more messages appear.

When the login screen finally appears, there are display turds near the
bottom of the region where the logo filled the screen. Then I log
in, use the (non-X11) console for a minute, and get the oops when the
display nears the bottom of the screen. I include the oops and the
"drivers/video/cfbimgblt.lst" -- no C code here for some reason.

I think that counts as three bugs: the white bits and display turds
can be ignored, the oops can't.

Known problems? Suggestions? Patches?
