 I think this is a known issue. If I am not mistaken, you will find
multiple threads about it.

Yes it's a recurrent problem

Do you use SMC2?

I think you have to validate both SMC1&2 to have your one SMC work
correctly, I use mpc8260ads and it's work fine for me.
I had this problem until i validate both SMC in arch/ppc/8260_io/uart.c.

did it work?

Subject: kernel on MPC8260ADS - character losing


Hello!

I'm trying to run 2.4.4 on MPC8260ADS.
PpcBoot works fine. After booting the kernel image
(Uncompressing Kernel Image ... OK) there is emitting of weird
characters; losing every second one, some are doubled as follows:

Did anybody experience such effect with serial port?
