After initial problems to get the R52n miniPCI card to work in STA mode on
a Ubiquity RouterStation I managed to get things working. (trunk r18127)
However during data transfer in /proc/memfree one sees from starting values
MemTotal:          62136 kB, MemFree:           41316 kB
the MemFree constantly reducing until, after about 450 MB of datatransfer from an AP
to this station at 10 Mbps effectively via sftp, MemFree reaches about 8 kB
and the kernel starts switching off applications and finally a reboot cannot be avoided.
One sees, while MemFree is reducing, from their initial values 
Slab:               7696 kB, SUnreclaim:         7020 kB both of these steadily increasing.
At MemFree:            3440 kB their values are Slab:              45836 kB SUnreclaim:        45156 kB

Any help welcome on how to go about figuring out what is consuming the memory until it is gone.

R54n in titele should be R52n
