I'm not sure if this is the right place for this, but I hope I can at least get
some pointers from someone.  I have a problem with the March 26 sources, and
the XFree 2.1 shared distribution on sun-lamp.  When I use xdm, I can start up
a session fine and dandy, but when I quit from the session the screen goes back
to the normal pc3 non-X terminal and just hangs.  No disk cache flushs, no
keyboard acknoledgement, just a good old solid hang.  I've checked the files
GiveConsole and TakeConsole, because it seemed like this is where it was
hanging but no luck, everything looked fine.  XFree86 2.0 worked fine on this
machine, so it isn't like it was something that didn't work before.  Xdm is
complaining about no meing able to mmap /dev/mem, but it seems if that was the
problem, then nothing should be working.  All other x programs work fine, and I
can compile tk, ghostview/ghostscript, fvwm without a problem and they also
work fine.  Can somebody give me a pointer on how I should go about fixing
this, because I am lost right now. 

Thanks,
Brian Moore
