This has been regressed from qemu 6.x. +Steps to reproduce: +1. Run the provided Kernel binary with the command line specified above. +2. Notice the hang after 'Initialize MMU'. I traced it down to being an instructions abort after the write to the SCTLR_EL1 register. +3. Try to run with qemu 6.x, and notice that it works. +Additional information: +This does work on actual hardware, so it has to be a qemu bug. + +A binary of the Serenity Kernel has been attached to the issue. The source of that binary can be found at commit ca0e32e59fcf67a662e5d3a994d44cd7c941624a of [SerenityOS](https://github.com/SerenityOS/serenity). + +[Kernel](/uploads/f731edbf81d8e575035e9693b0a51dbf/Kernel) |
