Hello Arnaud,

I didn't say the problem was just because of re(4). Actually i think the
there were two problems, one with re(4) and other with ata(4). The reason
why i talked about both of them in the same mail is because i thought
that as two drivers were affected, maybe the problem was in other part
of the operating system and that could help the developers to debug the

My re(4) card isn't sharing the interrupt with IXP600, it's sharing
the interrupt with USB controller. In this case i think the problem
is fixed with the advices from Pyun YongHyeon (backporting the driver
from HEAD and using MSI for interrupts).

I think the problems with ata(4) code will appear again after a few
days of load, as they always do, so i'll keep trying to debug them.
