    Hello Alex,

    Thank you for using Apple Support Communities. 

    I see that you have been getting the kernel panics when starting your computer and it has gotten worse under El Capitan. Since it started under Yosemite, I would recommend starting with basic troubleshooting for startup issues. See the following article for suggestions:

    Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support

    Cheers

    Thank for your suggestion.

    I followed steps but the situation is the same before. I found that the panic can be happened by third-party softwares or I/O devices. So I tried to reinstall my mac with new mac OS X 10.11. And then I installed some Apple's apps. After that the panic was happened again, but this time it seems to be by different reason:

    Hi Alex,

    Since the reason for the panic seems to be changing, this may not be the best way to assist you. It may be better if you get in contact with another one of our support resources. - https://getsupport.apple.com/GetproductgroupList.action.
