-> Does RM7000 O2 reveal the same symptom?  I guess the answer is no as RM7000
-> is the very straight forward descendent of 5000 and 52XX.

My guess would be "no" as well (though were there Rm7k O2s even made?) as
I believe the issues are mostly due to the speculative nature of the R10k
and lack of hardware cohorency.

My $0.02 marked down 50% since this has mostly been said before :-)
