Yes, I can reproduce it with your test, thanks. I'm on 6.4-rc still for $reasons (6.5 we skipped during vacations, and 6.6 EEVDF scheduler broke everything for hwsim tests in hostap), but this code didn't really change anyway. I'll poke at this. (And I'm still amazed that anyone other than me even uses this stuff :P) johannes _______________________________________________ linux-um mailing list linux-um@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-um
