I got the same issue.

Boot with option -x -v -f worked for me.

Got this upgrading my Mav Hack today. If you go verbose, it'll show you that it's "still waiting for root device." Rebooting with "-v UseKernelCache=No" worked for me. Of course I haven't rebooted it since :)

Just update mine today and somewhere in me said I should do some reliability tests and I did.

A couple of CPU and graphic stress tests. Used Davinci Resolve 11 to do some of the grading. Machine runs extremely smooth and nice.

Did a couple of boot tests. The first and second was great. Until the third, progress bar under the Apple logo run dramatically slow then out of nowhere this screen shown up.

Restart again, screen says can't find mach_kernel.

I booted with -x -v -f, got into safe mode, loaded my org.chameleon.Boot.plist, delete

<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string>nvda_drv=1</string>

Also changed UseKernelCache to No.

Did some restarts, machine runs beautifully.

Hope this could help some of you guys
