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. [8] 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 ...
In the event of a kernel crash, kdump preserves system consistency by booting another Linux kernel, which is known as the dump-capture kernel, and using it to export and save a memory dump. As a result, the system boots into a clean and reliable environment instead of relying on an already crashed kernel that may cause various issues, such as ...

mced [15] (mcedaemon) is a Linux program by Tim Hockin to gather MCEs from the kernel and alert interested applications. Note that it does not try to interpret the MCE data, it simply alerts other programs. mcat is a Windows command-line program from AMD to decode MCEs from AMD K8, Family 0x10 and 0x11 processors.
If the VirtualBox Debugger is open, a message is printed indicating a Triple fault has occurred, followed by a register dump and disassembly of the last instruction executed, similar to the output of the rg debugger command. When using Intel VT-x, a triple fault causes a VM exit, with exit reason 2. The exit reason is saved to the VMCS and may ...
The kerneloops software can collect and submit kernel oopses to a repository such as the www.kerneloops.org website, [7] which provides statistics and public access to reported oopses. A simplified crash screen was introduced in Linux 6.10, similar to the Blue Screen of Death on Windows. [8]
ProcDump is a command-line application used for monitoring an application for CPU spikes and creating crash dumps during a spike. [2] [3] The crash dumps can then be used by an administrator or software developer to determine the cause of the spike.
The Direct Rendering Manager and KMS are part of the Linux kernel. The KMS does only the mode setting. The KMS does only the mode setting. Mode setting is a software operation that activates a display mode (screen resolution, color depth, and refresh rate) for a computer's display controller by using VESA BIOS Extensions or UEFI Graphics ...
