Bugzilla Automation <bugzilla@FreeBSD.org> has asked freebsd-x11 (Nobody) <x11@FreeBSD.org> for maintainer-feedback: Bug 249476: graphics/drm-fbsd12.0-kmod i915kms GT2 attach returned 19 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D249476 --- Description --- Intel Haswell GT2 Server HD Graphics P4600 vendor=3D0x8086,dev=3D0x041a,rev= id=3D0x06 download.freebsd.org: FreeBSD 12.2-BETA1 r365618 GENERIC amd64 pkg.freebsd.org: FreeBSD:12:amd64/latest/All/drm-fbsd12.0-kmod-4.16.g20200221.txz Up to date as above. Modules kldload and kldstat ok... Loaded /.../i915kms.ko, id=3D8 i915kms.ko, drm.ko, linuxkpi.ko, linuxkpi_gplv2.ko, debugfs.ko But the only dmesg output says they are broken... kernel: anon_inodefs registered kernel: debugfs registered kernel: drmn0: <drmn> on vgapci0 kernel: device_attach: drmn0 attach returned 19 Then upon kldunload of i915kms it panics.

But they do throw some issues... kernel: info: [drm] Memory usable by graphics device =3D 2048M kernel: info: [drm] MTRR allocation failed. Graphics performance may suffe= r. kernel: error: [drm:pidxxx:i915_write32] *ERROR* Unknown unclaimed register before writing to c5100 ... kernel: error: [drm:pidxxx:drm_mm_takedown] *ERROR* Memory manager not clea= n.
