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...)
Odd. The bma250e is documented as having an id of 0xf9 not 0xf8.
http://ae-bst.resource.bosch.com/media/products/dokumente/bma250e/BST-BMA2
50 E-DS004-05_published.pdf
So all I can think of is that the chip is a bma222e (or something else
with the 0xf8 chip id) or there are some bma250e's out there with
the wrong ID...
Someone changed a part on the device and thought no one would notice
and hence didn't update the bios? (even if it has a totally different
range)
I guess if you frig the driver to load anyway we can see what value
it is giving for g and that should give us more of a clue.

Sorry, on webmail today and missed the existing follow ups!
Cheers
