And the UUID failure, \_SB_.PCI0:_OSC invalid UUID seems that the NEXP equal to 0, that cause firmware report invalid UUID, need firmware to check. If (LAnd (LEqual (Arg0, GUID), NEXP)) { ..... } Else { Or (CDW1, 0x04, CDW1) Return (Local0) }
This _OSC optional object is a control method that is used by OSPM to communicate to the platform the feature support or capabilities provided by a device’s driver. This object is a child object of a device and may also exist in the \_SB scope, where it can be used to convey platform wide OSPM capabilities. When supported, _OSC is invoked by OSPM immediately after placing the device in the D0 power state. Device specific objects are evaluated after _OSC invocation. This allows the values returned from other objects to be predicated on the OSPM feature support / capability information conveyed by _OSC. OSPM may evaluate _OSC multiple times to indicate changes in OSPM capability to the device but this may be precluded by specific device requirements. In summary, failing to evaluate _OSC may cause some features to be disabled. For instance, some advanced PCIe features such as ASPM or PCIE hotplug will be disabled. ** Changed in: linux-lts-saucy (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1287539 Title: [Dell Inspiron 7737] HIGH failures found in fwts report To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-saucy/+bug/1287539/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
