Surprisingly enough, this hasn't seemed to have bitten many Linux people yet, Google only finds a BSD thread (where the same ACPICA code is in use): http://comments.gmane.org/gmane.os.dragonfly-bsd.user/1817 I found this, but haven't tried it yet: commit 5f1cb4a92e4c4aabd139ff9ca1e11c0e2db2ac59 Author: Lv Zheng <lv.zheng@xxxxxxxxx> Date: Wed Feb 26 10:32:01 2014 +0800 ACPICA: Remove global option to serialize all control methods. With the addition of the auto-serialization feature, this option is obsolete and is completely removed. Lv Zheng. This patch also updates acpi_serialize kernel parameter using the new auto-serialization feature - acpi_gbl_auto_serialize_methods. This looks like a user nightmare waiting to happen, because: - acpi_serialize [HW,ACPI] force serialization of AML methods + acpi_serialize= [HW,ACPI] configure auto-serialization of AML methods Re-using a kernel parameter name with different semantics is just asking for trouble. I get this in my dmesg, and then I end up with all sorts of ACPI-related weirdness - everything from 4 or 5 temperature sensors evaporating to it claiming that my laptop doesn't have a battery bay (it may also be related to an issue I'm seeing with multiple graphics monitors as well, but I haven't verified that yet). We're going to need a better way to deal with this before it gets to mainline....
We have a commit that removes this command line argument already. But those messages:

shouldn't be there regardless. I'm going to look at this issue later today. Rafael -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
