It seems the problem that force_drivers line must not contain empty spaces, now it look like: force_drivers += "cros_ec_devs ptn3460 pwm-samsung" and correct one is force_drivers+="cros_ec_devs ptn3460 pwm-samsung" with such line, dracut parse force_drivers fine. > >> >> Guillaume >> >> >> >>> >>>> The boot (and reboot) problem is fixed with latest image. >>>> >>>> >>>> Guillaume >>>> >>>> >>>>> >>>>> Guillaume >>>>> >>>>> >>>>> Le 17/08/2015 17:27, Misha Komarovskiy a écrit : >>>>>> >>>>>> I can send patch to opensuse-kernel ml if thats suitable, this way is >>>>>> described on the wiki >>>>>> >>>>>> >>>>>> https://en.opensuse.org/openSUSE:Kernel_git#Submitting_your_changes_to_the_kernel_team >>>>>> What do you think is patch for lpae enough or better add default and >>>>>> vanilla also? >>>>>> --- >>>>>> Best Regards, >>>>>> Misha Komarovskiy >>>>>> zombahatgmaildotcom >>>>>> >>>>>> >>>>>> On Mon, Aug 17, 2015 at 5:59 PM, Guillaume Gardet >>>>>> <guillaume.gar...@free.fr> wrote: >>>>>>> >>>>>>> Thanks. >>>>>>> >>>>>>> Could you submit your patch to stable branch for default, lpae and >>>>>>> vanilla >>>>>>> flavours, please? >>>>>>> >>>>>>> Patches against master branch should follow once git repo fixed. >>>>>>> >>>>>>> >>>>>>> Guillaume >>>>>>> >>>>>>> >>>>>>> Le 17/08/2015 16:07, Misha Komarovskiy a écrit : >>>>>>>> >>>>>>>> My patch in attach >>>>>>>> --- >>>>>>>> Best Regards, >>>>>>>> Misha Komarovskiy >>>>>>>> zombahatgmaildotcom >>>>>>>> >>>>>>>> >>>>>>>> On Mon, Aug 17, 2015 at 4:13 PM, Guillaume Gardet >>>>>>>> <guillaume.gar...@free.fr> wrote: >>>>>>>>> >>>>>>>>> Perfect! >>>>>>>>> >>>>>>>>> I submitted an update request to include it: >>>>>>>>> https://build.opensuse.org/request/show/323645 >>>>>>>>> >>>>>>>>> We still need to update our kernel config to disable exynos IOMMU. >>>>>>>>> But >>>>>>>>> kernel repo is currently broken for master. >>>>>>>>> Could send your config patch against stable kernel (4.1), please? >>>>>>>>> >>>>>>>>> >>>>>>>>> Guillaume >>>>>>>>> >>>>>>>>> >>>>>>>>> >>>>>>>>> Le 17/08/2015 14:31, Misha Komarovskiy a écrit : >>>>>>>>>> >>>>>>>>>> Adding them with force_drivers do the trick. >>>>>>>>>> --- >>>>>>>>>> Best Regards, >>>>>>>>>> Misha Komarovskiy >>>>>>>>>> zombahatgmaildotcom >>>>>>>>>> >>>>>>>>>> >>>>>>>>>> On Mon, Aug 17, 2015 at 3:09 PM, Guillaume Gardet >>>>>>>>>> <guillaume.gar...@free.fr> wrote: >>>>>>>>>>> >>>>>>>>>>> You do not need to modify your kernel for that. >>>>>>>>>>> Remove your /etc/modules-load.d/ file to get back in non-auto >>>>>>>>>>> loading. >>>>>>>>>>> >>>>>>>>>>> Open the file '/etc/dracut.conf.d/exynos_modules.conf' and add the >>>>>>>>>>> following >>>>>>>>>>> line: >>>>>>>>>>> add_drivers += "cros_ec_devs ptn3460 pwm-samsung" >>>>>>>>>>> >>>>>>>>>>> Then recreate your initrd with: >>>>>>>>>>> dracut -f >>>>>>>>>>> and reboot. >>>>>>>>>>> >>>>>>>>>>> >>>>>>>>>>> If it does not help, replace: >>>>>>>>>>> add_drivers += "cros_ec_devs ptn3460 pwm-samsung" >>>>>>>>>>> by: >>>>>>>>>>> force_drivers += "cros_ec_devs ptn3460 pwm-samsung" >>>>>>>>>>> >>>>>>>>>>> Then recreate your initrd with: >>>>>>>>>>> dracut -f >>>>>>>>>>> and reboot. >>>>>>>>>>> >>>>>>>>>>> >>>>>>>>>>> Guillaume >>>>>>>>>>> >>>>>>>>>>> >>>>>>>>>>> >>>>>>>>>>> Le 17/08/2015 14:04, Misha Komarovskiy a écrit : >>>>>>>>>>>> >>>>>>>>>>>> I made test on already installed image.
