Hi,
cc'ing mailing list,
Daniel any ideas?
Nope, not really :( And no ideas how to triage this further - if it takes 9 days to hit it eventually we'll have a real hard time. Or does this happen even after just a short X run?
Seems to happen every time while stopping the x server. Also after a short run time.
The current fedora 3.11 kernel doesn't show this bug. I'm using fedora 19, with a self compiled kernel.
I did turn on config-debug-pagealloc but this didn't show any wrongness.
In that case I think the bisect is the fastest way to insight - atm I'm really at loss what could be wrong here.
From the error messages it looks like whatever's responsible for clearing page->mapping doesn't do it for these pages, (shmem code?).
