As soon as the system loads i915kms the console slows down until it freezes completely and the characters get garbled. Trying to switch tty doesn't have any effect. The only thing I can do is rebooting with the usual key combination.
This happens on both 15.0 and CURRENT. I have tried the drm-kmod package, the fresh drm-latest-kmod package, and also built the git port.The behavior is always the same. I'm on an HP All-in-one Intel Core 5 Ultra Meteor Lake.
