Hi.


Guys, I have a IBM system x 3560 server, it hangs, I was told to use the 
NMI button when it hangs, I found it and pressed, nothing happened. I 
reset the server, and pressed a NMI button after entering a multiuser. 
Nothing happened.

FreeBSD 9.1-PRERELEASE

Now questions:

- what should happen upon a NMI keypress ? I thought FreeBSD should 
panic and enter ddb (default sysctl settings). Am I wrong ? This kernel 
has kdb/ddb.
- does someone have IBM system x servers ? what happens when you press 
NMI  (IBM said it should reset, so be careful if you'll decide to 
experiment).

Thanks.
Eugene.
