Message-ID: <BANLkTinr34qmAE8RWVY0Wq_XMfOc0jTUzg@mail.gmail.com> Date: Tue, 10 May 2011 16:04:07 +0200 From: Stefan Majer <stefan.majer@...il.com> To: linux-net@...r.kernel.org, linux-kernel@...r.kernel.org Cc: ceph-devel@...r.kernel.org Subject: Kernel 2.6.38.6 page allocation failure (ixgbe) Hi, im running 4 nodes with ceph on top of btrfs with a dualport Intel X520 10Gb Ethernet Card with the latest 3.3.9 ixgbe driver. during benchmarks i get the following stack. I can easily reproduce this by simply running rados bench from a fast machine using this 4 nodes as ceph cluster. We saw this with stock ixgbe driver from 2.6.38.6 and with the latest 3.3.9 ixgbe. This kernel is tainted because we use fusion-io iodrives as journal devices for btrfs. Any hints to nail this down are welcome.
