logcat of few bootanimation cycles

Hi,
I'm testing Android 8.1 (oreo-x86 branch of android-x86)
with the following gfx stack:

- drm_hwcomposer of freedesktop.org (hwctwo enabled and also with robherring
branch handle-rework)
- latest gbm_gralloc (robherring branch handle-rework, but also happening with
branches prior to handle-rework)
- latest libdrm, but it happens will all releases from 2.4.89(and before) to
2.4.91
- latest kernel 4.17rc4, but it happens with all kernels

Hardware: Laptop Lenovo T460 with Skylake GT2

Synthomps: Bootanimation completes, but then the Android GUI hangs and
surfaceflinger service is killed, Bootanimations restarts (GUI bootloop)

Very difficult to get debug logs, about what is causing signal 1 (SIGHUP)
killing surfaceflinger, but I could finally trace it.

anywhere in the entire gfx stack, including userspace.

reassign to the right component if it's not a kernel issue.

to analyze gpu hangs, so please always attach it.
05-07 21:36:58.689     0     0 I         : [drm] GPU crash dump saved to
/sys/class/drm/card0/error
05-07 21:36:58.689     0     0 I i915 0000: 00:02.0: Resetting rcs0 after gpu
hang


logcat, dmesg and GPU crash dump /sys/class/drm/card0/error are provided.

Please help to identify the root cause as this is probably the only show
stopper preventing drm_hwcomposer (hwctwo) + gbm_gralloc + libdrm from booting
Android oreo-x86 with full freedesktop stack.

I am available to support further investigations and testing of patches
