Hello I'm using centos 7. At uncertain times I suddenly get the following error. The system is panic. Then it restarts automatically. I have updated the package ( pkla-check-auth ) but the problem persists. My virtualization environment is KVM. (Host Centos7 , Guest Centos7. Problem Guest VM) Can you help me ? rpm -qa |grep pkla polkit-pkla-compat-0.1-4.el7.x86_64 KERNEL: /usr/lib/debug/lib/modules/3.10.0-957.27.2.el7.x86_64/vmlinux DUMPFILE: /var/crash/127.0.0.1-2019-12-02-00:00:36/vmcore [PARTIAL DUMP] CPUS: 8 DATE: Mon Dec 2 00:00:15 2019 UPTIME: 10 days, 11:35:12 LOAD AVERAGE: 0.06, 0.55, 0.63 TASKS: 1545 NODENAME: AO101 RELEASE: 3.10.0-957.27.2.el7.x86_64 VERSION: #1 SMP Mon Jul 29 17:46:05 UTC 2019 MACHINE: x86_64 (3191 Mhz) MEMORY: 16 GB PANIC: "BUG: unable to handle kernel paging request at 0000000180200037" PID: 6461 COMMAND: "pkla-check-auth" TASK: ffff8dd98f3b2080 [THREAD_INFO: ffff8dd990e70000] CPU: 2 STATE: TASK_RUNNING (PANIC)
