 I just retried this with a current from a few hours ago, with a trimmed
 down kernel config, after setting ddb.onpanic=1 (it was zero before, oops).
 
 After quitting X, I see the usual messages X leaves on the console.
 I then wait 4 seconds (doing nothing), the screen goes black (perhaps
 because of "ddb.commandonenter=call ddb_vgapost;bt"?) and then I see
 the following backtrace (first line really is just a number, the "..."
 are to save typing):
 0xffff8000676f2000
 RADEON_READ_MM() at netbsd:...+0x20
 vblank_disable_fn() at netbsd:...+0xc6
 callout_softclock() at netbsd:...+0x25c
 softint_dispatch() at netbsd:...+0x82
 DDB lost frame for netbsd:Xsoftintr+0x50, trying 0xffff80006389ad70
 Xsoftintr() at netbsd:...+0x50
 bt>
 
 What else can I provide to track this down?
 
 Thanks,
  Thomas
