...ing Xen timer for CPU1 installing Xen timer for CPU2 installing Xen timer for CPU3 installing Xen timer for CPU4 installing Xen timer for CPU5 installing Xen timer for CPU6 Here is the screen shot: https://goo.gl/photos/yNQqaQY9bJBWQ84X8 It stops at CPU6. This is a dual socket server with 2x 6core L5639 CPUs (HT disabled). I'm surprised to see it stop at 6.

...on is: why does the VM run stable on xen1 while it crashes all the time on xen2. If I compare xen1 and xen2, only real difference is mainboard (Supermicro X8 on xen1; Supermicro X9 on xen2) and CPU (Xeon L5939 on xen1; E5-2609 on xen2) As a next step I'll put the harddisks into another X8/Xeon L5639 server system and try to reproduce the crashes there. My bet is that this system will not crash anymore. In other words, I guess that this very bug is only triggered with the X9 + E-2609 combination. > Can I do anything additional to help debugging the bug? Shall I report > it > to Xen u...

...+ and no errors found and the CPU has been replaced by a new one (same model). Still, the VM crash is reproducible. The hardware on the crashing system is: CPU: Intel Xeon E5-2609v2/4x2,5GHz Motherboard: Supermicro X9SRI-F For information, the hardware on non-crashing system is: CPU: Intel XEON L5639/6x2,13 GHz Motherboard: Supermicro X8STi > It seems like the crashes are related to a RT process, even though no > sched_fifo/rr processes are started on this system intentionally.

Apologies: I installed the newer -26 kernel and had not rebooted into it. The grub2 menu item should have been "CentOS Linux (4.9.20-25.el7.x86_64) 7 (Core)". I am currently restarting that remote affected system (unmodified grub2 entry first).
