The vboxdrv 7.2.8 kernel module on the 7.0.0-1-cachyos kernel prevents the system from booting. The update logs show no suspicious outputs. Adding module_blacklist=vboxdrv to the boot options solves the problem. The system fails the Loading Kernel Modules job, tries to skip it, then the udev segfaults, systemd crashes, and it tries this job again until it completely stall, and you have to force shut down the PC. Steps to reproduce: Have a 6.x-cachyos kernel Have the vboxdrv 7.2.6 module Run full system upgrade Fail to boot up, fixable with module_blacklist=vboxdrv My cachyos-bugreport.sh if it can be of any use: paste.cachyos.org 982d8bd Author: Gunwant Jain, A highly opinionated and minimalistic Pastebin. If you have a similar problem, there’s a temporary workaround. Basically, the problem is the vboxdrv kernel module. You can fix it by creating a file: /etc/modprobe.d/vbox-fix.conf and adding this line: blacklist vboxdrv However, this will prevent you vbox from working. This is a temporary workaround and we have to wait for a full fix.
