[PATCH] ktest.pl: Fix missing "end_monitor" when machine check fails
Posted by Steven Rostedt 2 years, 7 months ago
From: Steven Rostedt <rostedt@goodmis.org>

In the "reboot" command, it does a check of the machine to see if it is
still alive with a simple "ssh echo" command. If it fails, it will assume
that a normal "ssh reboot" is not possible and force a power cycle.

In this case, the "start_monitor" is executed, but the "end_monitor" is
not, and this causes the screen not to be given back to the console. That
is, after the test, a "reset" command needs to be performed, as "echo" is
turned off.

Fixes: 6474ace999edd ("ktest.pl: Powercycle the box on reboot if no connection can be made")

	"the screen will not be given back"

Will try to remember to update this when I import it.

Masami, I believe this will fix your issue with the console after running
the test.
