Both of my new co-op students have encountered this as well: after a panic (unrelated to the filesystem), SU+J fsck recovery runs at boot, and than many cylinder checksum warnings are emitted by the kernel. The students used the default installer configuration; it sounds like we should disable SU+J by default in the installer until this issue is addressed.
