We do have a BMC that comes from the vendor. I checked
with our CMC guy and it seemed there was no way to trigger
an NMI through IPMI, or to send the Magic SYSRQ sequence via
the IMPI SOL serious console.

BTW, the SYSRQ_ENABLED in /etc/sysconfig/sysctl is not set
by default. Any bad side effect of setting it?
