State-Changed-Why: 

Please give us the kernel dump!
For the other issues, you need to carefully tune your system for zfs when using arch i386.
As you haven't send a dmesg or any other useful information, we can only guess
about your problem but I'm wondering if you're using a Sil3112 or the like?
You can't be sure to have working memory just by successfully passing the POST phase. Please check your RAM using something like memtest86, first (assuming you're running x86 hardware as your report is not clear if you're seeing this on sparc or on x86).
Also please check if the error appearance changes when swapping RAM modules.
