Subject: Re: Linux 3.1-rc4

Hi,

the recent -rc4 fix ( Kamal Mostafa / i915: do not setup intel_backlight twice ) fixes an oops
described in https://bugzilla.kernel.org/show_bug.cgi?id=40892#c1 but the core error
"[drm:intel_dsm_platform_mux_info] *ERROR* MUX INFO call failed" still exists.

moreover there's a next crash in framebuffer code:
