Darwin Kernel Version 12.2.0: Sat Aug 25 00:50:49 PDT 2012; root:xnu_debug-2050.18.24~1/DEBUG_X86_64
with ZEVO Community Edition 1.1.1
without two-machine debugging.
Keyword slapdash – because single machine use of a kernel debug kit is not a proper approach. But for anyone who might find them useful, there's a collection of kernel panics at http://www.wuala.com/grahamperrin/public/2012/11/10/c/
I didn't work with that debug version of the kernel for long, only long enough to get an idea that it was impossible for ZEVO to dynamically mount the (CoreStorage encrypted) ZFS file system that I would normally use for my home directory. The ease and predictability of the panics may reflect both (a) my slapdash approach at the time; and (b) the relatively peculiar mix of software that I keep on my MacBookPro5,2.
Incidentally Apple's release of the Kernel Debug Kit for 12C60 was around six weeks later than its release of that build of OS X 10.8.2.
