2.6.32 is pretty old. Is there any specific reason for not using a recent kernel version? > The problem that I'm facing now is that when I try to run any process (may > be an ls, cat, or whatever), the response of the process is *very* slow > (something like 10 to 20 seconds for a ls). This sounds as if only the output to the (serial ?) console port was slow - typically this happens when there is a problem with interrupt assignment, and you receive charatcers only after each of these times out. > My question to all is, did anyone see something like this already? Besides We have seen this many times in the past, when interrupts were not working correctly. I recommend to check youyr device tree settings for these.

It is working and actively maintained, but 8xx is a platform that is more or less hopelessly obsoleted - nobody uses it in new designs any more, so there is little work going on with it in recent kernel versions (at least compared with other architectures). > Is it being actively tested / used today?

Check your interrupts.
