ls: Undefined PLT symbol "__ftr_read50" (symnum = 64)

[matthew sporleder <msporleder%gmail.com@localhost>]

My whole system is now giving:
ls: Undefined PLT symbol "__ftr_read50" (symnum = 64)

On any ls commands.  This is on my wd0 (cf card), sd0 (usb drive), and
sd1 (sd card).

Is there any way to determine what this state is?  umount-ing and
re-mounting my usb drive doesn't change anything.

ksh can tab-complete a directory listing.  If I give a specific file I
get results:
lurch# ls -l /netbsd
-rwxr-xr-x  1 root  wheel  10472907 Jul  5 23:21 /netbsd
ls: Undefined PLT symbol "__ftr_read50" (symnum = 64)

Did I lose a module or somehting?

thanks,
Matt
