Just in case anyone else on this list is running into similar issues, I can confirm that the patch appears to have resolved this. I’ve opened https://bugs.centos.org/view.php?id=13713 It was so bad that having the system under load (with rpmbuild) and opening another ssh window or two would almost always cause the oops. Cheers, Nathan From: CentOS-virt [mailto:centos-virt-bounces@xxxxxxxxxx] On Behalf Of Nathan March This appears to be a centos kernel issue rather than a xen one. https://lkml.org/lkml/2016/5/17/440 Digging through the posts and not clear why this never made it upstream… I’m going to apply that patch to my systems and see if it resolves, but won’t know for certain until a week or two of stability goes by. - Nathan From: CentOS-virt [mailto:centos-virt-bounces@xxxxxxxxxx] On Behalf Of Nathan March Hi, I’m seeing numerous crashes on the xen 4.6.6-1 / 4.6.6-2 releases, on both the 4.9.34-29 and 4.9.39-29 kernels. I’ve attached a txt with two different servers outputs. Xen-028: This crashed this morning while running 4.6.6-1 and 4.9.39-29 Xen-001: This crashed shortly after being upgraded to 4.6.6-2 and 4.9.34-29 Both are on different hardware platforms, and have had a long history of being stable until these upgrades. It sounds potentially related to https://kernel.googlesource.com/pub/scm/linux/kernel/git/tiwai/sound-unstable/+/9ce119f318ba1a07c29149301f1544b6c4bea52a%5E%21/ but I’ve confirmed this patch is in the above kernels. Any suggestions / thoughts? Cheers, Nathan |
