Comment (by waddlesplash):
ICIs taking 10ms is unbelievably ridiculous and should not occur. I know
kallisti5 runs Haiku on his Ryzen and does not have these problems, and
the same is true for other people running Haiku on 16 core+ systems. So
the real problem is probably that the ICIs are taking so long.
Have you tried this on master? There were some IDT issues that may
actually be related here which were fixed since the beta. Those seemed to
substantially improve performance even on multicore systems that worked
already.
