Do you mean the Zeph-Leo? The kernel panic was something like this:

Panic (cpu 0 caller 0x0036DAC7):"Process 1 exec of /sbin/launchd failed, errno 88\n"@/volumes/disk1s2/leo_xnu-1228/bsd/kern/kern_exec.c:2884

And I don't know, what exactly is supported on my actual osx86 version, but I heard, it should be one of the best.
