Hi Stefan / Gerry,
Happy to inform you i have tested stefan's backport-patches on Intel and AMD:
- Patches apply cleanly to kernel's 3.18.6 and 3.17.8 and compile. (hmm, 3.17 seems to be already EOL according to www.kernel.org ?) - Fixes the subtle issues i had.
So .. Tested-by: Sander Eikelenboom <linux@eikelenboom.it>
Thanks !
