If running X, the cursor stops moving and ctrl-alt-del, ctlr-alt-bs fails to free the system. If fdformat /dev/rfd0.1440 is attempted, 3 to 5 Vs are printed and then the system locks up hard. It requires a hardware reset to break the system free. The same actions running a UP will work fine. The UP configuration file is the same as the SMP configuration file with the exception that the UP has the SMP options commented out. >How-To-Repeat: See above. >Fix: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
