I don't really know. Our BSD machines don't frooze. :) Really, I didn't
have any production FreeBSD that froze. With 4.8 or 4.9 and Intel HTT
enabled there were reboots, but on good hardware FreeBSD runs stable.

The remote IPMI solution depends on the exact implementation. What I wrote
is only for the X2100M2 machines. IMHO If your machines has a bridge that
the OS cannot see (so the driver cannot take over) the remote console will
work fine.

For ipmi install /usr/ports/<somewhere>/ipmi-tool and you can monitor your
system with munin for example. My collegue wrote a munin plugin:
For FreeBSD you've to rewrite a little, but if you like I send you my
version for the X2100.

We would be very thankful if you send your ipmi output with your machine
or mainboard version. Then we can extend our plugin. :)
