Since either Developer Preview 2 or 3 I have a strange problem - a kernel panic occurs on each shutdown and each restart. In addition to that CMOS gets cleared on each shutdown (not on restart). The whole dump is available below. If anyone has the same problem, please provide info on which version of OS X it first happened, if it still happened in the latest you tried and which boot loader incl. version you use. It happened for me since DP2 or 3 all the way through to DP6, beta inclusive. I used quite a few Clover builds, v2795 and onwards. I didn't try the builds since v2800, but there is no sign that any of these could fix the problem (I will try them later, of course, probably in the evening); not even that Clover is the cause of the problem.
I might do some experiments with some DPs and Clover versions and will update the thread if I succeed. In mean time please share you experiences. Thank you!
