Agreed. 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.
