One of my machines has been crashing overnight every few days.  It 
seemed to be a hang; I finally realized that I should set ddb.onpanic 
to 0, since I wouldn't see a panic message while I was in X.  The 
backtrace indicates that the problem is in the ntfs code; I have
/windows mounted read-only, so I suspect it's dying during the daily 
job.  Is anyone else seeing anything like that?  I've built and booted 
a debugging kernel so I can get better diagnostic info (and I'll sendpr 
when I do), but I'm perplexed because I don't see this on any of my 
other similarly-configured -current machines.  (Btw, I don't know what 
the panic is; gdb didn't display it, and I haven't had the chance to 
figure out yet why not.)
