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.
