It is a bit of a weird situation. To better understand things this 
definitively should be a bug report. This can be created as well via:

https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.17/+filebug

If you could explain there what was the initial series the laptop was 
shipped with and roughly how you got to 25.10. Maybe also include the 
output of "dpkg -l|grep oem" to see which packages are special OEM ones 
(also which are missing).

Let us know the bug number here and we can move the discussion off-list.

Thanks,
