I've run into a very similar-sounding problem, but not since 7.0-RELEASE. One machine would appear to hang at the initial login prompt, nothing typed is echoed. However, a soft reset would then cause whatever was typed at the prompt to finally be displayed before the shutdown messages would be displayed. This would happen possibly 4 out of 10 times on one machine only whenever it included both SCHED_ULE and kbdmux(4). It never happened with SCHED_4BSD and kbdmux(4), as 7.0 shipped, and it never happened with SCHED_ULE only. So, I had to remove kbdmux(4) to use SCHED_ULE instead of SCHED_4BSD in 7.0 to avoid that intermittent problem just on that one machine. -- Skip
