Let me try to do some logical things. My kernel is now 4.1.1-2.g998afec-desktop from repositories/Kernel/Head/standard/ kernel-desktop-4.1.1-2.g998afec-x86_64.rpm . He is freezing. Running kernel is 4.1.1-1 desktop self comp. From kernel.org. 4.1.1 tar.xz If I compare /lib/modules/4.1.1-2.g998afec-desktop/kernel/drivers/md and /lib/modules/4.1.1-1-desktop/kernel/drivers/md , there are four drivers missing, because they are builtin (linear.ko and raid0.ko and raid1.ko and md-mod.ko), as I configured it and can find it in modules.builtin. (see comment #32) There are some added: dm-least-pending.ko and dm-log-writes.ko and dm-multipath.ko and dm-queue-length.ko and dm-service-time.ko. and md-cluster.ko . (due to config file) Takashi Iwai asked me, to change the config file, but I cannot see, how this should be helpful. The SUSE kernel kernel-deshtop-4.1.1-2.g998afec-x86_64.rpm is the generic one. And he should run in most cases also in mine too. What's about the line CONFIG_MD_AUTODETECT=y , which is missing in SUSE kernel , as you can see in comment #32 . Does this line have any function? This is the only difference, I could find. I would like to try a SUSE kernel with this line added. Possible? (I have to delete the SUSE kernel after such attempts, because grub2 tries always to resume with the highest kernel and this causes problems for me, as I often use the hibernate function.)
