It's a dual core 8th Gen Intel atom. In the future I will use a quad core atom and probably I will isolate a core. I will investigate on ipipe traces. I will let you know, but for me it's OK anyway. Il mer 10 apr 2019, 21:36 Jan Kiszka ha scritto: > On 10.04.19 21:26, cagnulein via Xeno

After 3 days of test (latency + windows 10 with cpu-z and stress test) I reached rare peaks of 130 us. For me it's OK but I think there is a small "regression" against the 4.9 Do you need any other test? R. Il lun 8 apr 2019, 12:13 Jan Kiszka ha scritto: > On 08.04.19 11:56, cagnulein wrote: >

Hi, yes I double checked the patch and it's applied correctly. Here you can find my config. CONFIG_DEBUG_STACKOVERFLOW is disabled. I can't get the uart on this system, is there any other way to catch log in this scenario? Why should I test the 4.4.y? 4.9.146 works fine on the same system (with
