            Bug ID: 246280
           Summary: ciss driver causes immediate system crash&reboot if
                    extern SAS cable unplugged
           Product: Base System
           Version: 12.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: pen at lysator.liu.se

If the SAS cable (or the I/O module on the D6020 fails) between a D6020
external SAS JBOB cabinet is unplugged the kernel panics & immediately reboots.
This is a bit annoying :-)

I've so far been unable to catch an error message since it reboots so quickly
but will try to have a serial console attached while unplugging a cable on a
test server...
