https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=191206 Jean-Sebastien Pedron <dumbbell@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|Needs Triage |In Discussion Assignee|freebsd-bugs@FreeBSD.org |dumbbell@FreeBSD.org --- Comment #1 from Jean-Sebastien Pedron <dumbbell@FreeBSD.org> --- Created attachment 143958 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=143958&action=edit Try to map Video BIOS in intel_bios.c By reading your dmesg, it seems neither the i915 driver nor the Radeon driver find the Video BIOS. In the i915 case, the card is initialized, but without output connectors. In the Radeon case, the driver aborts the initialization process. Currently, our i915 driver doesn't read the shadow copy of the Video BIOS, which is available at a fixed location in system memory if the card is the boot display. I attached patch which tries to map that Video BIOS shadow copy (only built-tested). Could you please try it? -- You are receiving this mail because: You are the assignee for the bug.
