Yeah, we are wondering ourselves about that. Could you try cherry-picking
commit ad10eb079c97e27b4d27bc755c605226ce1625de (update migrate type on pcp
when isolating) from git://github.com/mina86/linux-2.6.git? It probably
won't
apply cleanly but resolving the conflicts should not be hard
My understanding of that situation is that the page is on pcp list in which
cases it's page_private is not updated. Draining and the first patch in
the series (and also the commit I've pointed to above) are designed to fix
that but I'm unsure why they don't work all the time.

This commit adds the alloc_contig_range() function which tries
to allocate given range of pages. It tries to migrate all
already allocated pages that fall in the range thus freeing them.
Once all pages in the range are freed they are removed from the
