Subject: 2.6.32.5 regression: page allocation failure. order:1,

I recently upgraded our 24/7 server from 2.6.31.5 to 2.6.32.5.

Now, suddenly the logs are full of "page allocation failure. order:1",
and the odd "page allocation failure. order:4" failures.

Wow.  WTF happened in 2.6.32 ???

Downgrading now.

Logs available if you want them:  http://rtr.ca/2.6.32_page_alloc_fail_logs.txt
