Thank you for your answer. Now i got the information, you might have looked for!!!!!!!! First: it has nothing to do with the USB stick. I deleted the swap partition, from fstab too. I attached during boot nothing changed. But is has definitely something to do with the other swap partition! As it has something to with dracut and the SUSE version of it, I changed in /etc/dracut.conf.d/01-dist.conf the last line: # add_dracutmodules+=debug to add_dracutmodules+=debug. kernel 4.0.5-3.2 was installed with this new settings and booted and after some waiting, there came up the line, you can see on timeout.JPG( which is attached). After having downgraded YAST the partitioner is working again! So I can look into the partition table: The swap partition is part of an extended partition! SUSE kernel seems not to be able, to open this. Data of the extended partition shown by YAST(German version): Ger�t: /dev/md126p2 Gr��e: 250.00 GiB Verschl�sselt: Nein Ger�tepfad: Ger�te-ID 1: md-uuid-b054006e:7e450d85:de257e42:4a16c54e-part2 FS-ID: 0x0F Extended Dateisystem: Dateisystem: Einh�ngepunkt: UUID: Kennung: Ger�t: /dev/md126p5 Gr��e: 5.00 GiB Verschl�sselt: Nein Ger�tepfad: Ger�te-ID 1: md-uuid-b054006e:7e450d85:de257e42:4a16c54e-part5 FS-ID: 0x82 Linux swap Dateisystem: Dateisystem: Swap Einh�ngepunkt: swap UUID: df0343ee-74e3-4124-a8b2-7349d946e6a8 Kennung: swap Ger�t: /dev/md126p6 Gr��e: 20.01 GiB Verschl�sselt: Nein Ger�tepfad: Ger�te-ID 1: md-uuid-b054006e:7e450d85:de257e42:4a16c54e-part6 FS-ID: 0x0C Win95 FAT32 LBA Dateisystem: Dateisystem: FAT Einh�ngepunkt: UUID: 2F8B-210D Kennung: Ger�t: /dev/md126p7 Gr��e: 224.98 GiB Verschl�sselt: Nein Ger�tepfad: Ger�te-ID 1: md-uuid-b054006e:7e450d85:de257e42:4a16c54e-part7 FS-ID: 0x83 Linux native Dateisystem: Dateisystem: Ext4 Einh�ngepunkt: /home UUID: 70177251-9d78-4c95-ae66-7d829c8e6038 Kennung: home mp126p2 is mp126p5+mp126p6+mp126p7 So kernel has to add x2 in this case to the uuid, but there seems something to be wrong with it. The self compiled kernel has no problem with it, maybe I have builtin something? Or should be loaded to the SUSE kernel by dracut? I'm VERY interested in your reaction. Do you still need the initrd? In that case I have no idea, where to upload it, be maybe a compression should be possible?
