That is good. We are preparing a series of patches for xen-4.1.3. They should be out in next few days. Thanks for your help on testing. -Wei On 10/26/2011 09:12 AM, Sander Eikelenboom wrote: Hello Wei, Sorry you were right, i'm a bit accustomed that patches apply to the root of the project, this one was for /xen specifically.

Haven't tried rebooting a lot of times without iommu yet. (the reason i bought the 890fx board in the first place) Will try that a few times when i have some more time. -- Sander Wednesday, October 19, 2011, 6:38:38 PM, you wrote:It looks similar. Hi Sander, could you please test your system with the following options? 1. iommu=amd-iommu-perdev-intremap in xen.gz GRUB entry 2. pci=nosmi in pvops GRUB entry 3. iommu=0 in xen.gz GRUB entry [optional, only if (1) doesn't work for you] We were seeing an issue which was caused by messed-up interrupt remap table. George Dunlap's perdev interrupt map solved our problem.

It always seem to happen during or shortly after booting. When it doesn't occur then, it can run for at least several days/weeks (haven't seen it panic then). It doesn't seem to happen at a particular point at or shortly after booting, but it happens before starting any guests Unfortunately i haven't had serial console enabled at these times, but i have made some photo's. The first 3 times it locked completely before being able to print a stacktrace, the 4th time it did (although the photo is a bit unsharp). So all in all, it kind of strange, i hope you can figure something out from the stacktrace, if not, i will see if i can try with serial console attached. -- Sander_______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
