Package: linux-image-2.6.32-5-xen-amd64 Version: 2.6.32-23 Hi,
I just witnessed a strange situation - a domU had its kernel updated from 2.6.32-4-amd64 to 2.6.32-bpo.5-xen-amd64, and all seemed well, but after two hours it stopped responding on its (statically configured) eth0 device. tcpdump of the bridge and the vif on the dom0 said that everything was all right, the domU was making ARP requests for its gateway, and the gateway was responding, but then the domU would just repeat the same request, over and over again. That sounded to me like a xen-netfront problem. I happen to watch xen.git, so I know about this recent back-and-forth: http://git.kernel.org/?p=linux/kernel/git/jeremy/xen.git;a=shortlog;h=refs/heads/xen/netfront After September 10th this year, several bugs were identified in this new smartpoll logic. I then checked in our package, and we seem to be using an August 13th copy, so we're missing those. I'm not at all sure that this was the issue in my problem, because I don't completely grok all that stuff - I don't exactly know if xennet_interrupt() or smart_poll_function() are what's getting stuck in my use case - but debian/patches/features/all/xen/pvops.patch includes the smartpoll changes and plain drivers/net/xen-netfront.c doesn't, and the latter has worked fine for many months here while the former screwed us shortly after installation, so that's suspicious enough for me. Please update the kernel pvops patch to include the more recent xen/netfront branch - where the benefit is both in that known smartpoll bugs are fixed, and this new feature is turned off by default until upstream is more comfortable with it.
