If I have 'smt=on' but hyperthreading disabled in BIOS, the issues do not appear. I don't know if this is security-wise equivalent to 'smt=off'. I guess I would take the risk for the added performance anyways. Although I would have to do some benchmarks first: My old system (Qubes 3.2) has hyperthreading disabled too since whenever this update was. I have not noticed any performance drops. In fact, I lately was less annoyed by its performance. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
