Hi! I just upgraded my NetBSD desktop machine (ASRock mainboard with Celeron J1900 CPU) from 8.1/adm64 to 9.0. It ran X11 without any problems before, but now I have glitches. Lines of pixels are not updated correctly, as if parts of the screen are constantly XORed. It's hard to describe...
The onboard graphics seems to be detected correctly: Mar 3 21:40:51 itix /netbsd: [ 7.7395065] i915drmkms0: interrupting at ioapic0 pin 16 (i915drmkms0) Mar 3 21:40:51 itix /netbsd: [ 7.8195601] intelfb0 at i915drmkms0 Mar 3 21:40:51 itix /netbsd: [ 7.8295675] intelfb0: framebuffer at 0xffffa200636dc000, size 1280x1024, depth 32, stride 5120 A little bit later in /var/log/messages, this pops up: Mar 3 21:39:58 itix /netbsd: [ 34.0453419] kern info: [drm] stuck on blitter ring Mar 3 21:39:58 itix /netbsd: [ 34.0453419] kern info: [drm] GPU HANG: ecode 7:2:0x96fbfff7, reason: Ring hung, action: reset Mar 3 21:39:58 itix /netbsd: [ 34.0453419] kern error: [drm:(/usr/src/sys/external/bsd/drm2/dist/drm/i915/i915_gem.c:3196)i915_context_is_banned] *ERROR* gpu hanging too fast, banning!

I can't find it in any of the files in /var/log/, so I am not even sure about the full text or who I am supposed to contact. Any idea how to fix this? Should I give modular X from pkgsrc a try? -- Joern Clausen https://www.oe-files.de/photography/
