Endless loop at "swapoff" time

I'm running a linuxppc-2.4.18-rc1 kernel on a PPC405GP target and have
the following problem:

If i do a "swapoff -a" the command is stuck in an endless loop.
The rest of the system is still up and running besides the performance
loss caused by CPU and disk activity.

The problems seems to be that find_next_to_unuse() is not making any
progress (always returning the same value). This results in an endless
while loop in try_to_unuse().

Anybody else seeing this odd behavior?
