drm-current-kmod-4.16.g20190424 hangs

[Jakob Alvermark]

Hi,


When I upgraded -current to r346730 drm-current-kmod-4.16.g20190323 
wouldn't load, "device_attach: drmn0 attach returned 19"

So I upgraded drm-current-kmod to 4.16.g20190424.

It loads fine, but shortly after starting Xorg the screen freezes.

The only way out is pressing the power button, it shuts down cleanly.

/var/log/messages shows this:

kernel: [drm] GPU HANG: ecode 7:0:0x60ac6ee9, in Xorg [100385], reason: 
Hang on rcs0, action: reset
kernel: drmn0: Resetting chip after gpu hang
syslogd: last message repeated 1 times
kernel: drmn0: i915_reset_device timed out, cancelling all in-flight 
rendering.
kernel: .

Tried once more, same thing happened:

kernel: [drm] GPU HANG: ecode 7:0:0x86f2fffd, in Xorg [100491], reason: 
Hang on rcs0, action: reset
kernel: drmn0: Resetting chip after gpu hang
syslogd: last message repeated 1 times
kernel: drmn0: i915_reset_device timed out, cancelling all in-flight 
rendering.
kernel: .

Reverting back to drm-current-kmod-4.16.g20190323 and -current to 
r346593 (yay boot environments!) it is stable.

This is on a laptop with CPU: Intel(R) Pentium(R) CPU  N3540  @ 2.16GHz 
(2166.72-MHz K8-class CPU)
Baytrail graphics.
