fbcon rotation or cyblafb bugs?

[Knut Petersen]

Can anybody confirm that clockwise / counterclockwise console rotation 
is working
or not working for arbitrary virtual x resolutions? Using cyblafb I get 
solid lockups
for certain combinations of font height and vxres. It does work 
perfectly reliable for
other combinations. It would be really nice if someone could run a test 
like e.g.

%!/bin/bash
setfont ...
echo -e "3" > /sys/class/graphics/fb1/con_rotate 
COUNTER=1280
while [ $COUNTER -lt 4080 ]; do
	fbset -s -fb /dev/fb1 -vxres $COUNTER -vyres ...
	cat testfile
	let COUNTER=COUNTER+8
done
echo -e "1" > /sys/class/graphics/fb1/con_rotate
COUNTER=1280
while [ $COUNTER -lt 4080 ]; do
	fbset -s -fb /dev/fb1 -vxres $COUNTER -vyres ...
	cat testfile
	let COUNTER=COUNTER+8
done

with some fonts of different dimensions using some other driver that 
supports
x-panning.

Forget about that help request, my problems are caused by a hardware bug 
of the
cyberblade/i1 graphics core.

Whenever an imageblit tries to blit across  pixel colum 2048, the 
graphics engine locks up.
Rock solid. Isn´t that a nice christmas gift?
