'i915.lvds_use_ssc=0' 

it works fine...

There's a quirk in the 3.0 kernel which should set lvds_use_ssc automatically. If that release isn't working, please send along the output of 'lspci -n -v' so that we can check to make sure the IDs match the current quirk and add them if they're different.

Hi

Does the bug still happen with a recent Kernel and default module parameters?

If not, please provide the log files:
