Do you have a KVM ? Quite a few of those seem to tickle this printk.
No, regular old PS/2 keyboard, directly connected. Due to that exact
uneventfullness and having seen it reported before recently (*) I
assumed everyone was seeing this. If not, I guess I can try to narrow it
down.
It's easy to test for anyone willing: just boot with "root=/dev/null" or
something as a kernel param. The printk's are in sync with the panic
code blinking the leds.

Dmitry, could you ask Linus to pull the change? I find this to be an
exceedingly annoying bug. It's just so incredibly silly, having one part
of the kernel helpfully blink leds at you with another part going "hey,
dude! don't do that!"
