Lh7A404 framebuffer device output freezing

[Kaushik Sen <kaushik@xxxxxxxxxxxx>]

  Hi All,

 I have been working on the LH7A404 CPU with a LPD7a404 board.

 I'm able to boot both 2.6.19 and 2.6.18rc3 + lh.patch.gz
(ftp://ftp.buici.com/pub/arm/patch-linux-2.6.18-rc3/ms34) kernels and
 mount the rootfs from both initramfs & nfs through the serial console,
 and get the shell, but when the framebuffer console driver & lcd
 are enabled the kernel shows messages till the last step of init then
 freezes on executing the userspace busybox init. 

 The last bootmessage shown in the LCD is : 
 Freeing init memory 92k..

 The kernel commandline uses console = ttyAM1 115200n8 console= tty0

 The serial output can be obtained from the busybox init by
 changing the serial devices to their proper naming conventions for
 SHARP Serial drivers to ttyAMx, in the code. However is it possible
 that the framebuffer device available from tty0 cannot be accessed by
 the userspace programs, thus there is no more output..?


 If anybody has a clue to thesource of the above problems, please
help...

 Thanks in Advance 
 regards
 Kaushik
