*** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? ran the server for some days with KVM VMs on top * What exactly did you do (or not do) that was effective (or ineffective)? Tried to ssh + ping. * What was the outcome of this action? ssh session got stuck. Ping still worked. * What outcome did you expect instead? should work *** End of the template - remove these template lines *** -- Package-specific info: ** Version: Linux version 4.9.0-9-amd64 (debian-kernel@lists.debian.org) (gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1) ) #1 SMP Debian 4.9.168-1+deb9u2 (2019-05-13) ** Command line: BOOT_IMAGE=/vmlinuz-4.9.0-9-amd64 root=UUID=83dcd5bf-42df-4931-aa7a-e09d8ecf6bb5 ro nomodeset nohz=off panic=30 ** Not tainted ** Kernel log: (obtained via netconsole) Message from syslogd@golf at Jun 11 06:37:56 ... kernel:[1616241.072680] NMI watchdog: BUG: soft lockup - CPU#5 stuck for 22s!
