But no change. The kernel hangs completly (without oops or what so ever, even nmi-watchdog has no results). It happend when I started the connection (from a IW4965 card). Then started up a Kmail connection, start up a browser sessie. Stop Kmail, and start Kmail. It also happens when I do a hostapd start, hostapd stop, hostapd start. Its a IBM 206 eserver, with no X running on it. The card is a WMP300N.
