Hoi! I use Linux 2.6.15.4 (updating to 2.6.15.6 right now) on a compaq evo n400c. When I insert the compaq wl100 (802.11b) pcmcia card, my system freezes completly (it's an orinoco chip inside). I remember, that _this_ notebook with _this_ card freezed also with earlier Linux kernel versions. But it first freezes, when pcmcia is activated in Linux. System information: [11:27] hydrogenium:~% lspci | grep -i -e cardbus -e pcmcia 0000:00:04.0 CardBus bridge: Texas Instruments PCI1211 [11:26] hydrogenium:~% uname -a Linux hydrogenium 2.6.15.4 #2 PREEMPT Sun Feb 26 18:06:18 CET 2006 i686 GNU/Linux .config is attached. What else information do you need for debugging? Nico
