Hard system lockups with 10.1, probably drm/newcons/radeonkms-related

Hi folks,
With 10.1-RELEASE, I've enabled newcons at boot with
kern.vty="vt"
in loader.conf. With the latest Xorg/drm installed with pkg, I'm
seeing intermittent hangs and hard lockups of the system. I've
included the logs for one which recovered earlier today, but later
on it just locked up completely and I don't have logs for that
since I had to do a hard reset. I had to install and enable
hal+dbus to get a working keyboard and mouse when running X,
despite both working fine on the console!
Not sure what the trigger is. Possibly also related to input.
The first hard hang was after logging in with "mwm" via kdm4.
It didn't start mwm, so I ran "mwm&" in the xterm; it locked up when
I clicked and dragged the window title, i.e. when initiating the drag
event.
The second hang was while typing into a tmux session inside a
konsole window. Nothing particularly special happening at the
moment it locked up.
I'm happy to do further debugging, but given that it locks up the
whole system, I'm not sure how to go about getting any useful
information at that point.
The graphics card is an AMD Radeon HD 6800 Series using
/dev/dri/card0. Starting X11 automatically loads the needed
modules:

It worked perfectly for 5 hours after this recovery.
