[didier.mequignon@wanadoo.fr: Bug#70094: Pb with FBDev on Falcon/CT2]

Can someone arrange for an unstripped XF68_FBDev binary from the 3.3.6-10
sources for this gentleman?  I have no m68k box of my own to do so.
Running gdb on the stripped binary won't do any good at all.

Package: xserver-fbdev
Version: 3.3.6-10


I'am a new user of Linux68K, and I'am a programmer under TOS (Atari).
I have an Atari Falcon 030 with a Centurbo II (32 mb of Fast-Ram).
I have installed the base of XFree, but I have some problems for start it.
I obtain just a white screen during some seconds, and after a signal 11.
I have found all packages in the ftp.fr.debian.org in the directory
/debian/dists/potato/main/binary-m68k , Debian 2.2, kernel 2.2.10                                                                                                                                                             
This is the results in the xdm.log:

FBDev seems not likes my Centurbo II.
I have installed the package of gdb, start a cmd: 'gdb XF68_FBDev' > file.txt
And obtained this results, gdb seems not received others commands 
after the screen is changed to white, and CTRL-ALT-SUP not works.

It's the results with a screen in 16 colors.
When monochrome screen is used this is another function who causes the same

You can see this message in xdm.log:
(--) FBDev: Hardware accelerator: Atari Blitter
For information using the Blitter isn't possible with the Fast-ram
(works only with the ST-Ram) and the blitter can causes problems
on CT2: With some Falcons the blitter no works with a bus at 25 MHz 
(in turbo mode the bus of the CT2 is at 50 MHz and the bus of the Falcon
at 25 MHz).
CT2's users use NVDI under TOS (who not uses the Blitter), and the CPU 
at 50 MHz is more fast than the blitter. 
I think that the Blitter causes this crash (signal SIGSEGV), because this
problem not exists on TT (fast-ram without Blitter) and a normal Falcon
(Blitter but no fast-ram).
I haven't found a solution for remove the Blitter of the kernel.

This is my config of XF86Config, all values are set to default:

Any ideas ?
