Comment(by Quozl):

 Replying to [comment:15 dsd]:
 > (One thing that I found slightly surprising is that when the system
 hangs in this way, it stops suspending and resuming. Do we know why?)

 Yes.  Processes that update the X display hang.  One of these processes
 occurs in the suspend path.  Using serial console I've found the xsetroot
 process still present for as long as the hang persists.  When the hang
 ends, a suspend occurs again.  I don't know what condition causes the hang
 to end.

 Note that the /runin flag files can be created from Open Firmware before
 first boot, and this has the advantage of more closely resembling the test
 that is done in manufacturing:

 {{{
 ok to-file int:2,\versions\run\15\runin\aggressive
 ok to-file int:2,\versions\run\15\runin\force
 }}}
