iwi, hidden SSID and wpa_supplicant problem

I have the same problem with an IBM R50 laptop and the iwi driver. From
dmesg
iwi0: <Intel(R) PRO/Wireless 2915ABG> mem 0xc0214000-0xc0214fff irq 9 at
device 2.0 on pci2
I have never been able to connect to a hidden SSID without giving the
BSSID. If I give the BSSID I can get connection but it takes a long time
and is not reliable as the driver looses connection and failes to
re-connect after a while.
When connected to an AP that broadcasts the SSID I still lose connection
after a couple of hours and have to stop and restart the connection. Here
is the sequiece from the console:
iwi0: link state changed to DOWN
iwi0: scan stuck
iwi0: link state changed to UP
iwi0: link state changed to DOWN
iwi0: link state changed to UP
iwi0: firmware error

The first couple of times it recovers on it self but after receiving iwi0:
could not allocate firmware DMA memory I always have to restart the
connection manually.
The kernel is built with option INVARIANTS and option INVARIANT_SUPPORT.
