Weird (I hadn't seen that you reported the 9235 working...), I have IOMMU problems with a 9235... What system are you running it on (when you say "power box", is it a beefy x86 computer or literally a PowerPC)? For me, AMD 990FX chipset, latest master linux. My board works fine* on another non-IOMMU system. -- Jérôme * with issues with port multipliers Link to Benjamin's first message: https://lkml.org/lkml/2014/3/27/43
