Alton, Can you re-create with dmesg log level raised and logs moved to console instead of k-buffer (I am hoping to get some kernel debug log on console while reboot).
Step 1. Back_up the dmesg log step 2. Raise dmesg console level [root@dev-fedora ~]# dmesg --console-level=7 [root@dev-fedora ~]# sysctl kernel.printk kernel.printk = 7 4 1 7 (another option to try) Make dmesg to print on console [root@dev-fedora ~]# dmesg --console-on Note: --console-level and --console-on are mutually exclusive option so cannot be used together. step 3. [root@dev-fedora ~]# poweroff --reboot Please share your observation.
