Absolutely that is the goal! Here is an update for all of you.
It turns out this was not a “simple” timing issue as we originally had thought, which is why the investigation has been dragging on. We finally understand what is happening, have ideas on where/how it started, and are working on fixes and mitigations. The core issue is that starting in 13.2/13.2.1, updates done in the FPGA changed the current demand profile such that there is a “spikiness” to it which can lead to a failure of a voltage switcher under extremely particular circumstances. Updates done in 13.3 and 13.4 made this worse. 14.x improved the picture unintentionally but still is susceptible to the issue. There is a *lot* that goes into this, including SW interactions as well as HW voltage rail design. Throughout the investigation, we didn’t come across any classic “bugs” which would explain the issue, it really is a situation that depends on a large number of factors. Temperature, throughput demand, HW variation, feature set enabled (enabling VLAN and encryption had a definite impact on recreation in our lab). So, this explains the nature of why some may be more affected than others, and why as winter finally turned into winter in the US, the problem showed itself more here. We have implemented some ideas on how to address it and have had good results internally and have shared those loads with some specific customers. We are also working on a long term “fix” that will help deal with the volatility so that the issue doesn’t come back. We have internal test beds now for this issue which we will use for long term stability tests with this issue in mind. I’ll be at WISPAmerica and I expect that by then we’ll at least have an Open Beta refresh out that has had some soak time internally to increase our confidence in moving forward with a general release. We appreciate your patience, as well as help from those of you that have let us run test loads on your systems.
