Subject: [ruby-core:119897] [Ruby master Bug#20890] MacOS 15.1, Macbook pro 2024 m4, YJIT: Kernel Panic on network access, works w/o YJIT
Issue #20890 has been reported by markus_d (Markus Doits).

Bug #20890: MacOS 15.1, Macbook pro 2024 m4, YJIT: Kernel Panic on network access, works w/o YJIT
https://bugs.ruby-lang.org/issues/20890
* Author: markus_d (Markus Doits)
* Status: Open
* ruby -v: ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [arm64-darwin24]
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
I'm getting the following panic which seems like it happens on network access, but *only when YJIT is enabled*:
```
panic(cpu 15 caller 0xfffffe00509d800c): [SPTM] VIOLATION_ILLEGAL_SPRR_INDEX: sptm_map_page(sptm.c:406) - page_fte(0xfffffde005159750), page_fte->type(0xe), new_sprr_index(0x7), new_pte(0x6001145892ce43), vaddr(0x11c2c8000)

I have no problems with a Macbook pro 2023 m2 with the same configuration, event with YJIT.
I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins.
I compiled ruby w/o YJIT and the panics seem to be gone.
`ruby -v` is without YJIT (same revision with YJIT panics).
