Default [Help][KK4.4.2] Titanium Backup help - exhaustive system crashes on restoring SD apps

Hi, I'm trying to restore my apps base on new OS. Using Titanium Backup for that, because my apps largely exceed internal memory capacity I must have a significant amount installed on SD. Restoring this layout on old OS seemed to cause no problems and tho it took alot of time the batch finished happily. On KitKat restoring seems working well if restoring to insternal memory but restoring to SD card very often causes TB or Android to freeze, followed by sudden restart. I never experienced so extensive instability when restoring from TB. Dont know what's the culprit.
SD card seems accessible, IOscheduler deadline/1024. AJ kernel, UBL, CM11.
Any help to resolve this nightmare would be welcome.
