A month ago I had zfs running perfectly on many different i386 machines (albeit with some tweaking to kernel parameters). With a week-old current, it always panics sooner or later now, no matter how low I set the ARC cache size or maxvnodes or how much I pump into kmem_size. Now kmem_map panics are being reported on amd64, which was pretty much unheard of before. If I can track down the exact change I'll just back it out of my local tree. Craig
