I believe the issue is the system is still starting up, and thus has the kernel poking at things.
It shouldn't be. The kernel is completely done 'starting up', else all the /etc/rc.* files wouldn't have been run and init wouldn't have started spawning off gettys.
I'm referring to things that result in a lot of I/O activity which are started in the rc files (NFS, DNS, sendmail, etc.).
Sure, but none of those are going to compete with X for resources that 'conflict' or would cause lockups.
This jibes with his statement that manually starting the xdm from a root shell prompt on a relatively quiescent system "works". It is likely that it "works" only because there is not simultaneous activity.
Or there is a a race in the video/keyboard driver that is causing problems. X calls into the driver, so it's possible a missing spl() or somesuch is causing problem.
I doubt very much the problem is related to inb/outb, and is instead a just a 'bug'. :)
Maybe. I think we should hold off investing too much of ourselves into our respective theories until after he has done some of the tests I suggested.
Your tests won't prove anything one way or the other.
You should feel free to suggest tests, too, of course, since I could be wrong, no matter how "right" it feels to me.
I don't think we can 'test' this one to test any particular theory. Any test complex enough to point to a particular problem would be almost as complex as fixing the bug.
Instead, we should find someone with the knowledge (Kazu and/or Soren) and hardware to recreate and fix the problem.
