[Xen-devel] Re: Bug#599089: linux-image-2.6.32-5-xen-686: Kernel Panics when using NFS from DomU to Dom0
Hi Jason, Thanks for the report. You stack trace looks pretty similar to one reported upstream over the summer: http://lists.xensource.com/archives/html/xen-devel/2010-06/msg00831.html Unfortunately I don''t think anyone ever got to the bottom of the issue. Luckily I''ve been able to reproduce reasonably easily (it seems transfer from domU to dom0 is the key rather than vice versa). The stack trace shows that the kernel has hit a pretty rare code path. It is trying to copy domU skb data into dom0 memory because the skb has been in the dom0 network stack. It does this so that the guest memory can be returned to the guest so that it doesn''t all end up sitting in the dom0 network stack. Obviously something is going wrong with this. In addition to the kernel logging of the error I get this from the hypervisor: (XEN) mm.c:2062:d0 Error pfn 16d99: rd=ffff83011fefa000, od=0000000000000000, caf=180000000000000, taf=0000000000000000 (XEN) mm.c:658:d0 Could not get page ref for pfn 16d99 (XEN) mm.c:3621:d0 Could not get page for mach->phys update which is consistent with the kernel''s BUG_ON.

But I think we rely on that pretty heavily anyway. I''ve committed it with that change.

Where do you guys commit? I didn''t see it on the kernel git tree, and can''t find a debian one. Would this happen to make it into Squeeze soon? ETA? Save me the trouble of a recompile :) Cheers, Jay On 10-10-05 06:39 PM, Jeremy Fitzhardinge wrote:> On 10/05/2010 11:22 AM, Ian Campbell wrote: > >> On Tue, 2010-10-05 at 09:54 -0700, Jeremy Fitzhardinge wrote: >> >>> On 10/05/2010 02:52 AM, Ian Campbell wrote: >>> >>>> On Tue, 2010-10-05 at 10:47 +0100, Ian Campbell wrote: >>>> >>>>> In addition to the kernel logging of the error I get this from the >>>>> hypervisor: >>>>> (XEN) mm.c:2062:d0 Error pfn 16d99: rd=ffff83011fefa000, >>>>> od=0000000000000000, caf=180000000000000, taf=0000000000000000 >>>>> (XEN) mm.c:658:d0 Could not get page ref for pfn 16d99 >>>>> (XEN) mm.c:3621:d0 Could not get page for mach->phys update >>>>> >>>> Adding a bit more logging to the kernel I get: >>>> gnttb_copy_grant_page old c22ebcd8 P:0x1ec8e M:0xc499d F:0x41000000 >>>> gnttb_copy_grant_page new c2324ce0 P:0x1fe18 M:0x11cd32 F:0x40000000 >>>> (XEN) mm.c:2062:d0 Error pfn 1cd32: rd=ffff83011fefa000, od=0000000000000000, caf=180000000000000, taf=0000000000000000 >>>> (XEN) mm.c:658:d0 Could not get page ref for pfn 1cd32 >>>> (XEN) mm.c:3621:d0 Could not get page for mach->phys update >>>> >>>> Notice how MFN 0x11cd32 has become 0x1cd32 by the time it gets to the >>>> hypervisor! >>>> >>> Oy, more of these.

From there it will go into unstable/sid whenever 2.6.32-25 is uploaded and then it will propagate to testing/squeeze some time after that in the usual way. However once it is in unstable there should be nothing to stop you installing the package on a squeeze system. I don''t control the upload to sid schedule I''m afraid so I can''t really say when it will happen. Perhaps someone on debian-kernel will chime in.
