Hello List, On Saturday evening, I installed the latest kernel update on my laptop (kernel-default-devel-5.3.18-lp152.69.1.x86_64, Lenovo ThinkPad P53 with UEFI, Secure boot enabled, Trusted boot disabled). It replaced version 5.3.18-lp152.66-default. Package installation did not report anything unusual, but when booting the laptop on Sunday, I was greeted with an unfamiliar blue 'curses' prompt right after POST (and before the Grub menu): 'hit any key to enter MOK management' (this is the first time that I see this since upgrading the laptop from 15.1 to 15.2). Upon hitting a key, another pop-up menu was displayed, where I selected the "Continue boot" option. I then reached the usual Grub menu and attempted to boot, but the process then hung at "Loading ramdisk". Out of options, I performed a forced power-cycle and tried again: no more "MOK Management" menu, but the new kernel still fails to boot and hangs at the same spot. Selecting the earlier kernel in Grub still allows me to boot normally, thankfully. Has anyone else seen this? Depending on the replies, I'll file a bug if necessary. TIA Ph.
