Hi, we are seeing multiple kernel crashes on one debian jessie cluster, both with an older backports kernel (4.2) and a present one (4.3). Systems are farily new E5-2620 v3 Supermicro, running as Xen dom0 (4.4.1). Any idea what might be happening here? Thanks for any help Tim (Sorry for the weird formatting, I obtained the messages through the serial net console) Incident 1, Host xen1: Feb 5 08:52:16 10.15.19.1 [1540674.252834] general protection
