In a "dual kernel" layout, kdump uses kexec to boot another kernel and obtain a memory dump. [3]: 10 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.
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]
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 ...

Sparse is a computer software tool designed to find possible coding faults in the Linux kernel. [2] Unlike other such tools, this static analysis tool was initially designed to only flag constructs that were likely to be of interest to kernel developers, such as the mixing of pointers to user and kernel address spaces.
rasdaemon [8] is a RAS (reliability, availability and serviceability) logging tool for Linux. It records memory errors, using the EDAC tracing events. EDAC is a Linux kernel subsystem that handles detection of ECC errors from memory controllers for most chipsets on i386 and x86_64 architectures. EDAC drivers for other architectures like arm ...
[7] In UEFI systems, the Linux kernel can be executed directly by UEFI firmware via the EFI boot stub, [8] but usually uses GRUB 2 or systemd-boot as a bootloader. [9] [10] If UEFI Secure Boot is supported, a "shim" or "Preloader" is often booted by the UEFI before the bootloader or EFI-stub-bearing kernel. [11]
This allows drivers and devices outside of the mainline kernel to continue working after a Linux kernel upgrade. [ 3 ] Another benefit of DKMS is that it allows the installation of a new driver on an existing system, running an arbitrary kernel version, without any need for manual compilation or precompiled packages provided by the vendor.
