Hello, Starting an xterm takes more than a few seconds, starting chromium takes more than a minute. Yes, /dev/drm0 is owned by my user. I've done some more testing and found that not only X11, but everything is slow. Even mounting the partitions and starting the system services during startup. With top, CPU0 shows 85% sys even when everything is idle. However, the above only manifest when I do a _cold_ boot (both on AC and battery). When I reboot the system, everything behaves normal (i.e. fast) and CPU0 shows 0% sys. Furthermore, it doesn't matter if the reboot is done from OpenBSD or Windows. Kind regards, Martijn Rijkeboer
