I just upgraded my system to Mountain lion and I find that after I reboot a certain number of times it'll get into a cycle where the machine will be alive for about 10-15 seconds, and then it will just halt and reboot and continue that cycle until I Safe Boot, or boot my recovery partition and repair permissions, or reset the PRAM. It usually takes a combination of various things for this to finally work. I found some crash logs that point to ZFS causing this to happen when it tries to mount. In fact all of my kernel logs stop after the last file system is mounted. Attached is my crash report, which I have 3 separate instances of.
Under Lion I never had a single issue.
Some system details: Early 2009 Mac Pro with 4x1.5TB Seagate Barracuda drives in RAIDZ configuration. I have about 12 filesystems in the pool, occupying ~1.55 TB. I create snapshots regularly, and have them set as "visible".
My temporary workaround is to move the ZFS*.kext drivers out of System/Library/Extensions, and to load them by hand after the system is fully booted. I don't know why, but I haven't seen it crash with this method (yet).
Thanks,
John
