TL;DR
+1 to Mauricio's suggestion to disable it on all but x86 right now with this upload

Yeah, while we only have examples and reports on arm and riscv so far IIRC when Paride tracked this down back in the day upstreams statement was (sadly I can't find a link anymore where this happened) was more or less like "if at all it only works on x86". Hence we decided to better disable it on all non-x86 based on the reports we already have and that statement.
I'll ping Paride if he still has a reference where this came up, but it was quite some time ago so it might be lost due time.
