Comment # 5 on bug 1021306 from Takashi Iwai

Yeah, 2GB is very much enough! I thought it were in the level of a few MB :)

RC4 is already seen as fairly stable, so the breakage risk is very low.
If not, blame kernel people.

Just download kernel-default-4.10.rc4*.rpm from
  http://download.opensuse.org/repositories/Kernel:/HEAD/standard/x86_64/

then install it via
  zypper in kernel-default-4.10.rc4*.rpm

Reboot, and test it.  Once after checking whether the issue is present in 4.10
or not, you can uninstall it freely, simply by
  zypper rm kernel-default-4.10.rc4
