Touchpad not detected

Hi everyone,
Just upgraded from 15.0 to 15.1 yesterday. One issue that I am unable to solve: the touchpad isn’t detected anymore.
For information, I had to add ACPI=off to the kernel options, otherwise neither the live CD nor the installed version will boot. There was no such problem in 15.0.
Thanks in advance for any help.

You can try installing the latest kernel from the kernels repo

http://download.opensuse.org/repositories/Kernel:/stable/standard/

A newer kernel is more likely to recognize your hardware.
