After recompiling a kernel binary image from source code, a kernel panic while booting the resulting kernel is a common problem if the kernel was not correctly configured, compiled or installed. Add-on hardware or malfunctioning RAM could also be sources of fatal kernel errors during start up, due to incompatibility with the OS or a missing ...
Linux. systemd, a software suite providing system components for the Linux operating systems, implements a blue screen of death similar to those of Microsoft Windows using a systemd unit called systemd-bsod since August 2023, which was fully added on December 6, 2023 starting with version 255 of systemd.
On Linux, the kernel writes messages about MCEs to the kernel message log and the system console. When the MCEs are not fatal, they will also typically be copied to the system log and/or systemd journal .
The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts between different processes. [1] It is the portion of the operating system code that is always resident in memory [2] and ...
A general protection fault ( GPF) in the x86 instruction set architectures (ISAs) is a fault (a type of interrupt) initiated by ISA-defined protection mechanisms in response to an access violation caused by some running code, either in the kernel or a user program. The mechanism is first described in Intel manuals and datasheets for the Intel ...
One set of page table for use in kernel mode includes both kernel-space and user-space. The second set of page table for use in user mode contains a copy of user-space and a minimal set of kernel-space handling system calls and interrupts. Kernel page-table isolation ( KPTI or PTI, [1] previously called KAISER) [2] [3] is a Linux kernel feature ...
