When a kernel panic occurs in Mac OS X 10.2 through 10.7, the computer displays a multilingual message informing the user that they need to reboot the system. [16] Prior to 10.2, a more traditional Unix-style panic message was displayed; in 10.8 and later, the computer automatically reboots and the message is only displayed as a skippable ...
kdump (Linux) – Linux kernel's crash dump mechanism, which internally uses kexec System.map – contains mappings between symbol names and their addresses in memory, used to interpret oopses References
Checkpoint/Restore In Userspace (CRIU) (pronounced kree-oo, /kriu/), is a software tool for the Linux operating system. Using this tool, it is possible to freeze a running application (or part of it) and checkpoint it to persistent storage as a collection of files. One can then use the files to restore and run the application from the point it ...
IBM PC compatible hardware is one architecture Linux is commonly used on; on these systems, the BIOS or UEFI firmware plays an important role. In BIOS systems, the BIOS will respectively perform power-on self test (POST), which is to check the system hardware, then enumerate local device and finally initialize the system. [ 7 ]
This disallows a root user to load arbitrary code via kexec and execute it, complementing the UEFI secure boot and in-kernel security mechanisms for ensuring that only signed Linux kernel modules can be inserted into the running kernel. [4] [5] [6] Kexec is used by LinuxBoot to boot the main kernel from the Linux kernel located in the firmware.
Dirty COW (Dirty copy-on-write) is a computer security vulnerability of the Linux kernel that affected all Linux-based operating systems, including Android devices, that used older versions of the Linux kernel created before 2018.

In edge-triggered mode, a call to epoll_wait will return only when a new event is enqueued with the epoll object, while in level-triggered mode, epoll_wait will return as long as the condition holds. For instance, if a pipe registered with epoll has received data, a call to epoll_wait will return, signaling the presence of data to be read ...
