Let's start by understanding the problem description. + +The issue occurs when using QEMU 7.2.0 with a specific Buildroot configuration targeting x86-core2 and glibc. When booting the system, it crashes during initialization with segmentation faults in various processes like syslogd, klogd, logger, and eventually the init process. The kernel panics because init is killed. + +Looking at the provided logs, I see that multiple processes are failing due to general protection faults within libc.so.6. This suggests that there's a problem with how the system is executing user-space binaries, possibly related to CPU features or compatibility settings. + +The Buildroot configuration uses BR2_x86_core2, which specifies the Intel Core 2 processor as the target. This means that the toolchain and kernel are built with instructions compatible with Core 2 architecture. If QEMU isn't emulating the CPU correctly for this setup, it could cause issues when running user-space applications. + +In the bisect result, the problematic commit is 958e1dd1300f, which I should look into to understand what changed. From a quick glance at the commit message, if it's related to CPU emulation or instruction set changes in QEMU for x86 targets, that could explain the issue. + +Now, considering whether this is a user-mode or system-mode problem: User-mode issues typically relate to how applications run under the emulator, while system-mode relates to hardware emulation, devices, and OS-level interactions. Since the crash happens during init with processes failing in user-space (libc calls), it seems more like an issue with executing user-space code correctly. This points towards a problem in how QEMU handles user-mode execution for this specific CPU configuration. + +Additionally, reverting to QEMU 7.1.0 fixes the issue, which means something changed between 7.1 and 7.2 that affects compatibility with Core 2 emulation in user-mode applications. + +So, putting it all together: The problem is likely related to how QEMU emulates CPU instructions for user-space processes when targeting x86-core2. This would fall under user-mode issues because it's about executing applications correctly rather than system-level hardware interactions. +</think> + +user \ No newline at end of file |
