Hard to say, but it's very plausible. I don't understand why PS/2 is so painful to deal with. The Model M is known for its high current draw and is one of the keyboards that has the most trouble with PS/2 converters, but PS/2 converters are always hit and miss in general anyway. I have a Blue Cube (or two, I think) and that's meant to be the gold standard (even though it's a no-name product of completely unknown origin), but I have at least one keyboard where it simply won't work at all. For that, I need my Belkin, and that's a proper well-known brand and product, but it's the rubbish version that frequently hangs and then resets (the best version is reported to use the same converter chip as the blue cube). I plugged in some keyboard the other day using a Mechanical Keyboards (?) converter, and it was stone dead, so I had to try a different keyboard that would work.
Instability (spurious keystrokes/crazy behaviour) I thought was more likely to be a keyboard fault, but I can't recall the outcomes when it's occurred in the past, as I think that too may be resolved by trying another converter. It does happen from time to time.
What I do wonder, therefore: how does ADB compare for conversion reliability? You hear a lot less about ADB conversion, but I don't recall anyone having any trouble with it. PS/2 goes back to the 80s — it's hardly new, so after all this time, why is it so hard to implement?
