The original upstream bug fix was:
commit 3161e453e496eb5643faad30fff5a5ab183da0fe
Author: Rusty Russell <ru...@rustcorp.com.au>
Date: Wed Aug 26 12:22:32 2009 -0700
virtio: net refill on out-of-memory
which was included in Linux 2.6.31.
However, another fix was needed on top of that:
commit 39d321577405e8e269fd238b278aaf2425fa788a
Author: Herbert Xu <herb...@gondor.apana.org.au>
Date: Mon Jan 25 15:51:01 2010 -0800
virtio_net: Make delayed refill more reliable
I'll apply that and ask you to test the result.
