There's a lot of nice debug possibilities which can be enabled via the kernel command line. I would look closely at debug, earlyprintk= and edd= <https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html> I've never had any EDD issues, so I don't know how early that appears. But edd=off at the command line would be valuable to test as well. The earlyprintk is quite useful if issues appears very early in the boot process, and it has best benefit if you can hook up this against an external system (serial port, etc). Another thing to check is /proc/cmdline if you manage to boot the system using a SL install medium in rescue mode. Also check the kernel versions installed vs the one on the install medium. Using the install medium in rescue mode, it should be possible to mount the root file system in a chroot, where you can downgrade/upgrade the kernel if that is different from the install medium. Just my few cents of ideas ... -- kind regards, David Sommerseth
