I am using kernel 2.6.37, but I think it is not kernel issue, but more
bad patches done on kernel.
It is based on TI's kernel, but with some custom modifications on
driver's switch, to make it work with TI's cpsw switch.
Seems like someone made some bad patch, I'll continue investigating it.
You can ignore the question...

Many thanks a lot for the help,
