booting 2.6 kernel on ML403

[Pradeep Sampath]

Ameet,
  I was able to get the system to work today with your Sysace driver patch and was able to boot the ML403 with the correct 'root=' option. But the kernel crashes with a "Oops: machine check, sig: 7 [#1]". (I have 'nt applied the TEMAC patches yet)
  It appears that the xparamater definition file genearted using EDK 8.1 does not map correctly with the driver and it looks like i need to further downgrade the EDK to 7.1 and re-generate the BSP. I am attaching the console logs and xparamater file. please ignore my earlier reply.
   
  thanks
  Pradeep

  Pradeep,
What you have pasted is only part of the messages displayed. I can't 
tell anything from this apart from you 'root=' option. It would be nice 
if you could paste the entire log of the boot messages right from 
'loaded at: xxxxxxx xxxxxxxx' to 'Kernel Rebooting in 150 seconds'.
