It behaves a little differently. Before, it would clear the screen and get stuck. Now it shows this:

[ 36.067981] watchdog: BUG: soft lockup - CPU#5 stuck for 22s! [kworker/5:1:71]
[ 36.067983] watchdog: BUG: soft lockup - CPU#6 stuck for 22s! [thermald:1113]
[ 36.527766] NMI watchdog: Watchdog detected hard LOCKUP on cpu 0
[ 37.482793] NMI watchdog: Watchdog detected hard LOCKUP on cpu 3
[ 41.598740] NMI watchdog: Watchdog detected hard LOCKUP on cpu 1

Then there's a couple repeats of the first 2 lines at later times.
