Created attachment 61312 [details] Working 2.6.39 config The summary pretty much says it all. Linking barfed due to some Radeon DRM + backlight issue. From what I've read, similar issues have cropped up before but I have yet been able to find the root cause. I can say the problem did go away when I changed my config from CONFIG_FB=y to CONFIG_FB=m. I've attached my working config and the linking error is below. drivers/built-in.o: In function `radeon_lvds_enc_destroy': radeon_legacy_encoders.c:(.text+0x958ce): undefined reference to `backlight_device_unregister' drivers/built-in.o: In function `radeon_legacy_backlight_init': (.text+0x95a4c): undefined reference to `backlight_device_register'
