Hey, Running kernel 4.0.8 on a WinBook TW100 tablet, I get the error message in the subject line when loading the bmc150_accel driver. The 2 items in udev about that device: P: /devices/LNXSYSTM:00/LNXSYBUS:00/80860F41:04/BMA250E:00 E: DEVPATH=/devices/LNXSYSTM:00/LNXSYBUS:00/80860F41:04/BMA250E:00 E: MODALIAS=acpi:BMA250E:BMA250E: E: SUBSYSTEM=acpi and: P: /devices/platform/80860F41:04/i2c-12/i2c-BMA250E:00 E: DEVPATH=/devices/platform/80860F41:04/i2c-12/i2c-BMA250E:00 E: MODALIAS=acpi:BMA250E:BMA250E: E: SUBSYSTEM=i2c And the DSDT for the device: https://people.gnome.org/~hadess/Winbook%20TW100%20DSDT.dsl Any ideas what I should try (apart from a more recent kernel, I'm onto that...)
