Yes, it's seems to me too that problem is mainly in interaction between APM and PC Card. So: 1. ThinkPad hangs when I remove 3C589D while APM enabled (apmconf -e) 2. If APM disabled ThinkPad doesn't hang up when I remove 3c589D for the first time. (in case when pccardd doesn't run anything except echo). 3. ThinkPad hangs up when I try to remove 3C589D for the second time. 4. ThinkPad doesn't hangs up when I try to remove 3c589D after I'd ran 'ifconfig ep0 inet ...', 'ifconfig ep0 delete'. 5. ThinkPad hangs up when I try to remove 3c589D after I'd ran 'ifconfig ep0 inet ...', ping, 'ifconfig ep0 delete' - after some network activity. 6. When I go to suspend mode, kernel unload ep0, return irq, disable slot. After resume kernel insert card, and load ep0. 7. Keys that switch CPU to SMM mode works while hang ups. I'll to look two modem cards. And I'll try to install PAO. PAO's pccardc allows to power off card before removing, may be it helps. with best regards, Igor Sysoev To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
