https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220384 Bug ID: 220384 Summary: Loading kernel module i915 after i915kms panics Product: Base System Version: 11.0-RELEASE Hardware: i386 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: martin@sugioarto.com Hi, this happens on 11.0-RELEASE and 11.1-BETA2. Even more annoying is that Xorg xf86-video-intel driver loads both kernel modules and causes the same panic (since March this year). I reduced it to a simple sequence of kldload comma= nds. Steps to reproduce (on many systems one of the modules is already loaded in /boot/loader.conf): 1) kldload i915kms 2) kldload i915 Both modules want to install the device /dev/dri/card0 which causes a clash (errno EEXIST) and a subsequent panic. Stack trace: make_dev_sv make_dev drm_attach i915_attach device_attach ... Panic message: panic: make_dev_sv: bad si_name (error=3D17, si_name=3Ddri/card0) Expected behavior: Only one of the kernel modules should load. The other subsequent kldload sh= ould fail to load without causing a panic. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
