This is more than just a dmesg difference, I assume? As in, you can
actually tell the difference in time it takes?

yes - I can actually see individual cells (the 'ok's) in the table being rendered separately.

This is across a serial line, at 115 kbaud, if that matters..

[ 22.762505] A-B-C-A-B-C deadlock: ok | ok | ok | ok | ok | ok | [ 26.589133] A-B-B-C-C-D-D-A deadlock: ok | ok | ok | ok | ok | ok | [ 31.854688] A-B-C-D-B-D-D-A deadlock: ok | ok | ok | ok | ok | ok |
