http://bugzilla.opensuse.org/show_bug.cgi?id=1209440 Bug ID: 1209440 Summary: After Kernel Update to 5.14.21-150400.24.49-default, boot fails hard Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.4 Hardware: x86-64 OS: openSUSE Leap 15.4 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: thomi.schmid@swissonline.ch QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0 Build Identifier: I have updated the Leap 15.4 kernel today, 17.03.2023, ca. 17:00 on 2 machines (desktop with Intel Core i5-6400, laptop with Intel Core i3-1005G1) from "5.14.21-150400.24.46-default" to "5.14.21-150400.24.49-default". Download and install went OK, but after the restart, the PCs stopped booting after GRUB having the new kernel selected and after showing the first initial kernel message "x86/cpu: SGX disabled by BIOS" There they hung hard, i.e. not reaction on keyboard, no blinking keyboard LEDs. Both PC needed to be turned off and on again to restart, where the same problem occurred again. Both PCs could then be restarted again with no error using the previous kernel "5.14.21-150400.24.46-default". Reproducible: Always Steps to Reproduce: 1.Install kernel 5.14.21-150400.24.49-default using YaST Online Update 2.Reboot PC 3.Select kernel 5.14.21-150400.24.49-default in GRUB 4.Boot selected kernel 5.14.21-150400.24.49-default Actual Results: PC hangs after first kernel message on screen Keyboard "dead": No keyboard LEDs (NumLock), no LEDs blinking Expected Results: PC should have booted successfully using kernel 5.14.21-150400.24.49-default Happend on 2 different PCs (older desktop, laptop) Happens everytime PC is "dead" and needs power off/on to restart -> Ctrl-Alt-Del is not working -- You are receiving this mail because: You are the assignee for the bug.
