Your log looks perfectly good to me, the part about not mounting devices 4...7 is OK since that ony applies for people who have larger number of partitions. (unless you DO have partion 4, which you well should have if you have Nemo or Sailfish installed...) As for booting the device, I can see from your log that the booting kernels are found correctly: Feb 16 06:56:37 (none) user.notice root: Loading kernel /boot/Harmattan/boot/zImage_2.6.32.54-openmode_l2fix Feb 16 06:59:03 (none) user.notice root: Loading kernel /boot/Sailfish/boot/bzImage Now there's one thing I do not understand, where is the device loading the Sailfish kernel from since you do not have partition 4? Do you have some nonstandard system in place? Or have you replaced your Harmattan on mmcblk0p2 with Sailfish? And if you have, then where is it loading your Harmattan kernel from?? Could you show me your ubiboot.conf, have you made some mofification there? Further on, if you have problem with booting Harmattan, are your preinit files correctly installed? Usually when kernel is loaded correctly but device hangs with black screen, the reason is missing/corrupted/permissions of /sbin/preinit_harmattan file.
