kernel hangs at my_console_write

Hello,

I am using the Hardhat 1.2 kernel from MVista on my custom board with
MPC855T. The kernel executes and hangs at my_console_write routine. I
did see someone else have a similar problem with the kernel. But I've
not seen any solution for the problem. The 1.1 from Hardhat works just
fine.

Thank you,
Navin Boppuri

I am using the Hardhat 1.2 kernel from MVista on my custom board with
MPC855T. The kernel executes and hangs at my_console_write routine.
We were using a slightly different kernel (2.4.5 + patches), but we saw a
hang in console_write when we didn't have our Baud Rate Generator clock
frequency correct.  In the version we were using, the numbers in
embed_config() seemed to indicate that Hz were desired, but after grepping
around, we saw that some parts of the kernel wanted Mhz.  Once we fixed
that, we got console output and things worked.

Hope this helps,

If you take everything from the same kernel baseline, all of this will
match.  At one point late in the 2.3.xx development, the values
were changed from MHz to Hz.  People weren't patching/merging
correctly to get all of the right parts at the same time.
