Kernel panic in macOS causing hard system hang #93
Description
Currently trying to emulate an x86-based system using QEMU with HAXM on macOS. When using the HAXM accelerator, I'm able to cause a reproducible kernel panic which results in an entire system hard reset (making debugging a significant challenge). Appears to be related to the test instruction, or emulation thereof. Thanks!
