I had the following error from the kernel in /var/log/messages:

Are you able to test this patch?
Thanks for the patch. I can test it, but so far I have been unable to reproduce the allocation failure on the unpatched kernel. Do you have any idea what I need to do to see the allocation failure again on the unpatched kernel before I try the patch?

No. I saw a few memory allocation failures in random places and there was no working steps to reproduce to any of them :(
Since this is issue is not reproducible, I will only post patch upstream, without applying it to fedora kernel.
Thanks for reporting.
