From fb4002d54b25ab70d46649a76bf536c67cb92bf4 Mon Sep 17 00:00:00 2001 From: Ian Moffett Date: Fri, 16 May 2025 20:07:43 -0400 Subject: kernel: Add cpu_halt_others() and harden panic() Ensure interrupts are disabled at the start of panic() to prevent any interrupts from further degrading the state of the system. Also adds a newline before "panic: " to clean up the logs.
