https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249922 --- Comment #2 from Jan Beich <jbeich@FreeBSD.org> --- Also, try upgrading to -CURRENT because drm-fbsd11.2-kmod and drm-fbsd12.0-kmod are unlikely to be fixed unless you provide a patch. According to the manpage SNA stands for Sandybridge's New Acceleration. GM45 (Gen4) predates Sandybridge (Gen6). Upstream has a lot of code to support gen4 and gen >= 045 in particular. However, bug 214593 disabled SNA by default due to crashes on pre-Sandybridge. If drm-kmod made SNA work but has graphical glitches then it's an improvement. This is why trying newer DRM drivers (i915kms, radeonkms, etc) even on old handware is important. -- You are receiving this mail because: You are the assignee for the bug.help
