I'm not interested in resuming after a real crash. The idea is to get suspend/resume functionality without hardware support. So there would be no panic, but the system would be brought to a halt and the memory dumped. > Also the devices wouldn't be in the state they had been in at > the time of the panic, so if you could get as far as the > reloaded kernel actualy doing anything, you'd either crash again > or risk corrupting things horribly. That's why they would have to be reinitialized. -- Christian Laursen _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
