I went through changes between 3.2 and 3.3, but from the descriptions nothing was really jumping out. So I fear the only way to isolate it will be a bisect. It will be taking its time since usually there are about 10-12 iterations if 3.3-rc1 is the first one working. Might be a bit less if it wo

Ok, so something between 3.2 and 3.3 which obviously has not been considered as stable material. As said, it usually turns out that 3.3-rc1 is ok, too. I'd love to be wrong there but... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. h

Hm, one change to think of would be 2e2fb75475c2fc74c98100f1468c8195fee49f3b xen/setup: Populate freed MFNs from non-RAM E820 entries and gaps to E820 RAM That would be in with v3.5-rc3. A final proof usually needs to bisect it. To narrow down the attempts there you could try various kernels fro

The LTS backport kernels are mainly hardware enablement options. But the Precise kernel is still a supported option, so if possible we want bugs fixed (if possible == if not requiring half of the next kernel backported). OK, so that range appears in the 1-1 mappings but seems not to be freed and t

Okay - I wasn't sure that it was so clear! I thought there was a plan to backport the quantal kernel to precise as the LTS, but anyway! See attached for the xen dmesg and host dmesg from a successful boot with original Xen and quantal kernel. ** Attachment added: "working_dmesg.log" https://b

The question can clearly answered with yes. The slight confusion was that during all the comments it was not clear to me whether the Quantal kernel was indeed used without or with the dom0_mem option. I took Mike's comment as if it was only *with* this option. Personally I find the usage of "unusab

We've already identified that a quantal development kernel (linux- image-3.5.0-22-generic) works with no dom0_mem option, so I imagine that the latest kernel would also work - is there a particular version that you'd like me to try? If xen upstream thinks the kernel should be fixed, then is questi

One thing for clarification. When using the unpatched xen-hypervisor and a recent kernel (like v3.8) from http://kernel.ubuntu.com/~kernel- ppa/mainline/ and no dom0_mem option on the affected machine. Does that still crash the same? -- You received this bug notification because you are a member

In upstream discussion this seems to be seen as something that should rather get fixed in the kernel and not the hypervisor. I will see what ideas come up there and get back with an updated change to test. Stay tuned... -- You received this bug notification because you are a member of Ubuntu Bugs
