Hello, I had installed OpenBSD 6.1 on a Dell Latitude E7470 laptop (amd64, Skylake architecture). It could work on it but there were some shortcomings (video was slow).
Today I upgraded to the latest snapshot, and I have rebooted successfully, once, after which I updated packages. When I boot up the system now, it gets stuck at the kernel messages, the last three lines being (typing it over): vmm0 at mainbus0: VMX/EPI error: [drm:pid96670:intel_dp_link_training_clock_recovery] *ERROR* too many full retries, give up error: [drm:pid96670:intel_dp_set_idle_link_train] *ERROR* Timed out waiting for DP idle patterns I do not remember what I have done to break the system. There are several reasons why I think it is my fault, and not a bug: 1. I have booted once successfully in the system (and everything worked great); 2. it happens also for the old kernel (obsd) (and also bsd.sp). A package upgrade cannot break the system to this extend. What could it be then? It would be difficult to include dmesg etc., because the system doesn't boot up. - Marco
