Multiple kernel oops'es: 2.0.27

I got three this morning by ftpd and ftp, one by ncftp (on Jan 13). This
is the first time ftpd, ftp or ncftp has oops'ed my kernel, so I'm not
sure how repeatable this is... I did try to ftp localhost after the
oops, and both ftp and ftpd oops'ed after I logged in and attempted an
'ls'. I'm not a kernel expert, so can someone make sense of this?

This was on a P100 using a SMC8216C ethernet card. If anyone wants my
kernel config, just let me know.
