I'm running kernel 4.7/stable.
It's installed from Opensuse packages atm.
Using the current kernel causes a crash when booting Xen 4.7 on UEFI. Referenced in this now ridiculously-long thread
https://lists.xenproject.org/archives/html/xen-devel/2016-07/msg02758.html
In hunting down the problem, this specific code was asked about @ 'xen-devel' ML,
@ https://lists.xenproject.org/archives/html/xen-devel/2016-07/msg02928.html
While I see that you're running linux-4.7 could you please double-check that it has the following:
commit 55f1ea15216a5a14c96738bd5284100a00ffa9dc Author: Vitaly Kuznetsov <vkuznets@xxxxxxxxxx> Date: Tue May 31 11:23:43 2016 +0100
efi: Fix for_each_efi_memory_desc_in_map() for empty memmaps
A patch to the patch was proposed @ 'xen-devel' ML,
https://lists.xen.org/archives/html/xen-devel/2016-08/msg00399.html
It seems to fix the problem. Boot to Xen with kernel 4.7 no longer crashes.
But then THAT patched patch was questioned @ 'opensuse-kernel' ML
https://lists.xenproject.org/archives/html/xen-devel/2016-08/msg00747.html
I'd just like to get to a correct fix & get it into upstream kernel, since that is what I'm told we need to wait for to get packages from the distro that have the patch & work.
Since it seems it IS a kernel problem, I was hoping someone here could help shortcircuit this back & forth between projects and get the fix into kernel code.
Thanks.
