2.1.63: Unable to handle ...

Hello,

I get a reproduceable Oops while executing a configure script (from
the arena web browser). According to sh -x the last commend executed
is `test -f /usr/bin/find'. This command causes the same oops on its
own as well, after that the shell is gone.
Linux 2.1.63, UP, compiled with egcs-2.90.10p, oops has no bad side effects.
Hopefully someone knows what `<c4800fc8/1ee3a02c>' means. I looked into
/proc/ksyms, the surrounding entries are

c021acec tty_std_termios
c4805048 init_nls_cp437 [nls_cp437]

Regards
Steffen
