Hi,

aluminum# uname -a
NetBSD aluminum.miller.net 1.6K NetBSD 1.6K (MYKERNEL) #0:

I accidentally hit Ctrl+Alt+Esc when I meant to type Ctrl+Alt+F1.
I discovered that hitting Ctrl+Alt+Esc crashes my system reliably,
where "reliably" means five times in a row.  

Although I am having Really A Lot of Fun with NetBSD, I don't know
very much at all about what I am doing.  Therefore, there is a 
high probability that I have done something wrong.  

Is the following information helpful?

Is there any additional helpful information I could provide?

I send my thanks to everyone involved with NetBSD!

Kindest regards,
