Package: linux-image-3.16.0-4 Version: 3.16.43-2+deb8u5
Severity: critical In the past weeks, I'm experiencing data loss (screwed up file systems; ext4/xfs/zfs affected) when migrating Stretch DomU Xen virtual machines from one Xen host to another. This happens on solid long-time stable Xen host systems (one cluster is based on wheezy with Xen 4.1.2 and a iscsi SAN shared storage which wasn't touched for ages, and two others based on recent Stretch). Apparently, only VMs with Kernel 3.16 are affected. Since VM migration is performed infrequently and VMs affected are long-running servers that are only updated once in a while I can't nail down a version when things started to go wrong. AFAIR a machine with 3.16.36 was migrating flawlessly some months ago, but recently showed corruption with a 3.16.43 kernel that was installed in September.
