I got tired of waiting for fsck's and have been using zfs for both my i386 
laptop and amd64 media server. I had a couple panics on the media server 
before I upgraded to 4gb of ram, but basically none since then. On the 
laptop, I can't recall having any, and it only has 1.5gb.

I think that by the design of zfs, the panic might not even have a chance 
of damaging your data, only losing a write that had not completed, but I 
can't say I am an expert.

In short, it has not given me any problems at all on two different 
configurations.
