So. I managed to copy all content of my Macintosh HD into backup folder on external hard drive. Afterwards I formatted my HD and tried to reinstall Mac OS. And here come troubles. I have same problem as I described in original post: when my mac is about to power off during shutdown sequence, I got kernel panic. After several kernel panics my mac doesn't boot again. Disk Utility says "Key not valid". AAAARRRRRGH!!!!
Resetting of PRAM and SMC doesn't help. Here is some information about kernel panic after another reinstallation of Mac OS:
Interval Since Last Panic Report: 83 sec
Panics Since Last Report: 2
