Q: Kernel Panic - imac rebooting please help?

Hello

My 2009 iMac continues to reboot due to kernel panic during the past couple of week. It happes several times a day. I cannot find any specific cause and it seems to happen randomly. That is even when the computer is on standby. I hvae searched the web, but cannot find a solution. The problem is getting worse.

I have tried apple hardware test that detected no problems. I have upgraded the imac last yaer with a Samsung SSD and its running 6 gb ram. It has worked flawless until now. Should I consider buying a new Imac?

Here is the log:
