Okay, next round: This time, 2.6.32-19 and virtio in guest, 2.6.32-18 in the host and sadly, it's not fixed: [ 159.772700] rdiff-backup.bi: page allocation failure. order:0, mode:0x20 [ 159.772708] Pid: 2524, comm: rdiff-backup.bi Not tainted 2.6.32-5-amd64 #1 [ 159.772710] Call Trace: [ 159.7

This is not the same bug as was originally reported, which is that virtio_net failed to retry refilling its RX buffer ring. That is definitely fixed. So I'm treating this as a new bug report, #592187. On Sat, 2010-08-07 at 18:17 +0200, Lukas Kolbe wrote: > Am Samstag, den 07.08.2010, 12:18 +0100
