Ok, I just built a 4.9.65 kernel with this patch on top and the config from debian (config-4.9.0-4-amd64). It applies without complaints: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5e25f5db6abb96ca8ee2aaedcb863daa6dfcc07a With the 4.9.51-1 from Stretch I can reliably reproduce the broken CPU counters after doing live migration with Xen once or maybe twice. The 4.9.65 + steal time patch survived throwing it around >20 times now, and there's no sign of any weird behaviour any more. Counters in /proc/stat keep showing values that still make sense, instead of suddenly jumping to values like 1174983480817 or 1753913027832... How do we proceed from here? -- Hans van Kranenburg
