Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.0 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  unsupported baytrail tablet

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  This is a tablet like the Terra PAD 1061 from Wortmann  designed for
  Windows 8.1.

  What doesn't work :
   - no sound (no card detected)
   - no wireless (no interface detected, the chip is Realtek RTL8723BS)
   - unstable clocksource (tsc should be used instead of refined-jiffies)
   - mmc errors (this is a Samsung chip KLMCG8GEAC, I think this is related to the bug #1422338)
   - power button not handled
   - battery not detected
   - internal webcam not detected
   - trying to install Ubuntu leads to a grub-installer error (cf bug #1451473)
   - and probably more, but I think its enough for now

  What works :
   - graphical card (intel HD) / screen / backlight
   - usb3
   - touchscreen
