radeonfb bug: text ends up scrolling in the middle of tux.

radeonfb bug: text ends up scrolling in the middle of tux.

[Dan Merillat]

Ok, I've poked around but I can't find a penguin or tux bitmap to
figure out why scrolling is so broken.  I've got to login blind and type
reset to get the console back.  Needless to say, no kernel messages
are readable after the mode-switch (they all overwrite themselves on
a single line)

This is recent 2.4.X kernels (up to and including .15-pre6)  An annoying
bug, be good to catch it before final.

Type 'dmesg' as root to get all your lost kernel messages back. Hopefully 
they'll shed some light on the problem.

Yes, yes.  The boot messages are normal, and typing 'reset' once I login 
restores normal console.  The code that sets up a scrolling window below tux
is well, missing the mark.

Tux looks like he's about 5 lines high, so lines 1-3 are tux, 4 is the one
line of scroll, 5 is his feet, and 6-30 is the previous kernel boot
messages.

Yes, I encontered the same. See my previous message for a patch:

Message-ID: <20011118163244.A1100@pinguin.subspace.exe>
Subject: Debugging (?) output in 2.4.14 breaks radeon framebuffer

The offending code seems to have entered the kernel at 2.4.14,
2.4.13 was OK on my box.

I can't seem to find that patch. This bug is annoying, can you please
tell me where I can get it?

Thanks, Louis
