Power failure shouldn't kill a filesystem, and generally shouldn't eat data that was written to disk before the failure. (Although I could complain all day here about why corruption happens anyway when you do any kind of out-of-order operations... I am looking forward to that Reiser4 transaction API, so we can finally get rid of the tmpfile+rename hack.) But in any case, there were some kernels -- 2.4.16, I think? -- in which reiserfs was unstable and did corrupt easily. I believe that was tracked down to kernel bugs outside of reiserfs.
