I've run into this before . . . in some cases FreeBSD doesn't properly reset hardware. This is definately true (historically at least) of some PCMCIA devices; most likely it's true of others as well. When you do a cold boot, the loss of power is guaranteed to reset all the devices, but a warm boot may fail to reset some things. The problem is at shutdown, not bootup; I know this because if I was booted under Windows and warm-booted into FreeBSD or Windows, it would be ok, but if I was in FreeBSD and warm-booted into Windows or FreeBSD, it would lock up. I solved it by aliasing "reboot" to "shutdown -p now" myself. > > allison > > > > _________________________________________________________________ > 您可以在 MSN Hotmail 站点 http://www.hotmail.com/cn 免费收发电子邮件 > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message -- Brian T.
