    In case B freezes for some reason. Has happened to me a few times

    But I suppose you could just directly go for REISUO in that case.

    You're busier or is that a typo for "bustier"?

    @kescherRant not quite. Servers are quite sensitive to storage. And the more sophisticated storage solution is being used, the more unexpected problems can they cause.

    This usually happened to me when either SAN (veritas) switches were flapping or HBAs were malfunctioning.

    Storage malfunctions can cause unexpected errors :) Storage can even make `ls` crash your system for good. Yes, this has happened too :) Storage can corrupt your `reboot` execution or, in some rare cases, storage drivers (due to storage HW issues) can prevent sysrq+B from rebooting the machine.

    @cafecortado Add this to your GRUB command-line:

    sysrq_always_enabled=1
