Subject: ipw2100 0.61 losing SSIDs

lately, I have some trouble with the ipw2100-driver losing the SSID of known 
networks. With 0.61, this is 100% reproducable for me by loading the driver 
with "associate=0" and doing an iwlist scan after some seconds: All results 
appear with 'ESSID:"<hidden>"'. Without the additional parameter it is just 
harder to show up, but occassionaly I can see lost SSIDs there, too.

dmesg shows:

It is always the same pattern: Network gets added with SSID, losing it on the 
next beacon. Can anyone confirm this problem?
