I had tons of wierd boot/reboot issues with my old dell precision m4800. It stuck before boot and required voodoo rituals to finally boot successfully into linux or windows. Now it wasn’t used for some years and having installed recently a modern linux it works just fine now, like never before. As if the computer finally fixed itself.

More likely your updated Linux kernel checks for those specific bugs in those specific ACPI tables. If it finds them, it tells the kernel to ignore them and replace them with driver code. And then they actually bothered to test the driver code and make sure that it actually works.
