I was able to get to desktop using -x boot flag. Then i tried to open safari, it started showed a complete black window then i had a kernel panic again.
Something that i realized was there were no hdd icons on desktop, only cd icon. I opened my home folder via finder icon and saw that my disks (at the left pane) were all external type disk icons. I ran the system in AHCI mode btw. Any suggestions?
