Not sure if I'm seeing this same problem [1], but it doesn't appear fixed to me.
I've tried both mainline -rc2 and -next.
[1]https://lkml.org/lkml/2013/3/12/376
Without this patch, PG2.0 was not usable as CPSW interrupt was never acked
and CPU spent most of the time in CPSW ISR.
I have checked -rc2 and it is working fine.
