After doing an update to the new kernel and filesystems, I started
seeing strange things when running from an SD card. nvi was
segfaulting. I compared the md5sum for nvi on the SD and straight from
the debian-sarge tarball and they did not match. Turned out to be a
bad SD card. I wrote a bash script that runs md5sum on every file in
the tarball and compares it to the related file on the SD card, which
turned up a bunch of corrupted files.

I don't know if your problem is related, but it's worth checking that
the ping program (or a library it uses) has not been corrupted.
