Hi All,

I just finished porting linux kernel 2.6.15 to a MIPS based board. The
board now boots up beautifully ... and here is the console log:

Algorithmics/MIPS FPU Emulator v1.5

Next, I expected to see a command prompt which never comes. At this
point if I debug, I find the processor executing the idle process.

I am successfully hable to telnet to the board and fire whatever
commands I want though. How do I bring the prompt to the serial

My root FS seems OK since the same root FS is working for the same
board for an ancient kernel (2.4.20)

Any ideas, anyone?
