I maintain a fleet of very old 64-bit laptops in various conditions for events for youth. I use a set of custom installation and configuration scripts to install Fedora + Cinnamon DE.
When debugging an issue on two machines, I discovered that using 'acpi=off' as a kernel parameter breaks every BIOS installation I have, and some UEFI too. Some UEFI installations just have low resolution, or respond noticeably slower. Some UEFI and some BIOS installations freeze somewhere during the boot sequence. (haven“t examined more closely) And most of the BIOS installations boot, but fail to display the GUI. The TTY1 ends in some non-interactive state, but not frozen (still can display incoming systemd journal messages etc.). I can switch to other TTYs, where there is a TUI login prompt and the system is normally accessible from there. I carefully examined the kernel messages and systemd journal, both with extra verbosity levels. Nothing seems wrong there. The multi-user.target was reached, all services are fine, none related errors or unusual warnings, all necessary packages seem to be installed, ... My first question is whether it is expected that 'acpi=off' will prevent the BIOS installations from displaying GUI. Or if any of you can reproduce at all. My second question is how to further debug and where to look. Most of the BIOS systems work completely normal when 'acpi=off' is NOT specified. I fixed one machine by setting 'acpi=on' (which leads to a different result than not specifying the acpi kernel option value at all) and I have one machine that shows the exact same symptom, but the cause doesn't seem to be 'acpi=...' related, as any possible value won't help.
