Hello all,
I'm looking for hints on a curious problem.
I have a working kernel on a custom embedded device and it works fine.
We came up with a variation of the device with a few hardware changes, one of them being the number of serial ports that goes from 4 to 2.

In order to save time I tried my current kernel. When I boot the custom bootlader behaves the same, then the kernel boot behaves the same, but then once usermode is reached (the message "init started: BusyBox..."), the new card console display crawls to a halt (about one character per second instead of 115000 bauds !!!). But the card goes at normal speed as an ssh connection shows.

So my question is: is it caused by the fact that there are 2 missing serial ports ? Will making a new kernel with the correct hardware definition solve it ?
