[User-mode-linux-user] Problems with a newly build mkrootfs-made filesystem

[Jeff D. <jd...@ka...>]

Basically, the kernel doesn't boot on them.  I didn't test this explicitly 
because the filesystem that I do most of my testing on is a mkrootfs-made 
filesystem from a while ago.  I've added a bunch of things by hand (like 
swapping, virtual console, Apache) since then, and something in there is 
making it a lot less likely that the kernel hits the bug.

As far as I've diagnosed it, a process ends up with a page mapped that its 
page tables don't know about.  It's a page left over from something else, and 
it contains garbage, as far as the process is concerned.
