I experience similar issue with HD4730, although lockup is rather unavoidable
than "hard to trigger".
Booting with radeon.dpm=1 and two monitors attached results in periodic (every
15-45 sec) lockups (for ~7-15 sec), until one of them results in a reboot (most
of the time during bootup, before even X is started).
radeon.dpm=0 seems to boot up and work fine (although I think I had
unexplainable loud fan spinups after some time, need to test that further).
Bisecting kernel didn't yield anything useful. It just pointed me at
66229b200598a3b66b839d1759ff3f5b17ac5639 "drm/radeon/kms: add dpm support for
rv7xx (v4)".
Latest drm-next kernel (commit ef64cf9d06049e4e9df661f3be60b217e476bee1) didn't
help either.
The abovementioned patch for fixing arrays' size applied over 66229b2 didn't
alleviate the problem in the slightest (gcc 4.7.3 though).
Funnily enough, if I boot with either of monitors detached, it boots and works
fine, and if I then reattach the second monitor and connect it with xrandr,
everything keeps working fine. Disconnecting a monitor every time one needs to
reboot is a drag, though.
