 From the original report:

> VmallocChunk:      83764 kB

So it seems there's quite a bit of free space.

Chunk is the largest free contiguous region, right?  If so, it seems the 
problem is unrelated to guard pages, instead the search isn't finding a 
1-page area (with two guard pages) for some reason, even though lots of 
free space is available.
