Re: kvm causing memory corruption? now 2.6.26-rc8

So, just a continuation of what we were talking about before...

I just had a bug triggered on my system because I'm running sparsemem
(it was in show_mem()). I wonder if sparsemem is contributing to the
bug. Does kvm ever do any arithmetic that you can think of with 'struct
page's?

To summarize my config:
* 4GB of RAM
* hole from 3-4GB (so ram ranges from 0-5GB)
* PAE enabled
* SPARSEMEM=y

I'm compiling a kernel right now to try without sparsemem.
