I'm running 10.8.2 and ZEVO CE 1.1.1 on a hackintosh, and have my home directory on a zfs filesystem.
I could reliably get kernel panics if (don't laugh) I played Call of Duty 4. I never got any logs and could not produce kernel panics with disk torture tests (nor did I get panics when playing CoD4 without ZEVO installed). I chalked that up to a sign that I should be doing something else.
My system is very reliable, except every few weeks the filesystem becomes unresponsive. That's the state it's in right now. If I type 'ls' in my home directory, it hangs. I can't open new terminal windows because it stalls forever on my dotfiles.
What kind of data can I gather that would help to diagnose this? Hopefully I can get something useful before my system becomes completely useless and needs a reboot. If it matters, what triggered my zfs filesystem becoming unresponsive was doing a 'git pull' in a repo that lives in an encfs filesystem, provided by Fuse4X, and the backing store for encfs lives in my Dropbox folder.
