If the system is still usable when you type 'go' and the amount of data
is smaller than the kernel log buffer then set LOGGING=1.  The data
will be written to the kernel log and then to syslog after you type
'go'.  In most cases, a debug session has no working I/O so the kernel
log is not written to disk and is lost.  Then you have to use a serial
console (Documentation/serial-console.txt), debug over the serial line
and capture the output on a second machine.
