Note that the lspci output and the [ 1795.275026] [drm:hsw_unclaimed_reg_clear] *ERROR* Unknown unclaimed register before writing to 70084 line suggests HSW and the specs for ThinkPad Yoga suggests the same. But I don't know how the vlv_* functions can possible end up in those traces then, perhaps just a coincidence, random data on stack? For HSW the rc6 kernel option shouldn't make a difference. --Imre -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
