Yes, I can confirm that this problem is still present in 2.4.21-bk14.
See http://www.cs.helsinki.fi/linux/linux-kernel/2003-28/0165.html
for the details of my hardware.

Will this be fixed before 2.4.22 comes out?

bye lars

Ok, your problem is weird and doesn't seem related to others I've been
reported, I suspect some engine initialization issue. Do you have a
pointer to a specific -ac patch that caused it with earlier versions
of the driver ? That would help tracking down what change actually
introduced it.

Ben.

Interesting, I hadn't even bothered to try X at this point, was using 
the console exclusively.  Giving X a whirl, I see what you mean - it 
leaves the screen an unreadable pixel soup upon return to console mode.  
Oddly though, in my case, neither switching consoles nor a gratuitous 
fbset had any effect (though I didn't try all that exhaustively).

OK, per request, output from 'dmesg' attached in its entirety.

The system is based around a Soltek SL75-DRV2 motherboard with an Athlon 
XP, VIA KT266A/8233 and one of the early-production clock-reduced Radeon 
8500LEE boards that were sold initially in Japan (if you believe the 
user-comments on the newegg.com website).

Thanks for investigating!

This looks like erase not working properly... This usually happens
after switching back from X as X tends to leave some garbage in some
engine registers, and is usually cured by switching to another console
(this is why I tend to force-reinit the accel engine on console switch).

Since your problem seem to not depend on XFree, I suspect something
else hairy is going on with the engine, I don't know what yet though,
I'll try to find some clue.

In the meantime, can you send me a dmesg output ?

Thanks,
Ben.

Ben, Ani, et al,

Just tried Linux kernels 2.4.21pre6 and pre7 with my Radeon 8500LEE and
have had some dreadful corruption problems related to pixel clearing
during scroll and ypan.  This is probably old news to you; so <aol>me
too</aol>.  I first noticed this in the -ac kernels, but a variant is
now in mainline -pre.

Problem #1:  When scrolling, radeonfb fails to erase the portion of the
screen at the bottom, leaving all sorts of random pixels in the bottom
line.  Further scrolling propagates these pixels upwards.
See http://enterprise.bidmc.harvard.edu/~ktk/temp/radeonfb/screen-1.jpg
(Sorry for camera-shake; hand-held in dim room...)

Problem #2:  When one VC has scrolled up some number of lines, causing
it to display somewhere in the middle of its virtual Y buffer, and you
switch consoles to one that is still displaying from some other Y-start
value, the screen tends to redraw itself in an odd location (not at the
bottom) thus leaving large portions as they were from the previous VC.
See: http://enterprise.bidmc.harvard.edu/~ktk/temp/radeonfb/screen-2.jpg

Problem #3:  Possibly a side-effect of problem #2, when switching VCs
via Alt-<F1...Fn> the new VC often fails to appear.  The cursor
disappears, but the screen remains as it was.  Hitting <Enter> to scroll
the screen has no effect.  Interestingly, pressing <Alt>-<SysRQ>-? to
get a magic-sysrq help line restores the screen to operation, and it
displays all further output normally.  This occurs perhaps 50% of the
time.

Workaround #1:  Setting vyres == yres causes the aforementioned issues
to go away.  However, it also takes accelerated scrolling with it.
# fbset -vyres 10240
# time locate xine
[lots of screen output]

real	0m0.935s
# fbset -vyres 1024
# time locate xine
[lots of screen output]

real	0m2.548s
#

Problem #4:  I think this was already reported.  But when running X,
switching to a text console (with <Ctrl>-<Alt>-<F1...Fn>) results in
complete corruption of the output.

HTH,
Kris Karas
