After restarting, it shows a message for a few seconds informing the user that a problem caused the computer to restart, before continuing to boot. The message now includes a Chinese translation. If five new kernel panics occur within three minutes of the first one, the Mac will display a prohibitory sign for thirty seconds, and then shut down ...
runit is an init and service management scheme for Unix-like operating systems that initializes, supervises, and ends processes throughout the operating system.Runit is a reimplementation of the daemontools [3] process supervision toolkit that runs on many Linux-based operating systems, as well as BSD, and Solaris operating systems.
The Linux kernel has a "no-hlt" option telling Linux to run an infinite loop instead of using HLT, which allows users of these broken chips to use Linux. [16] The 80286 has the undocumented opcode 0F 04, causing the CPU to hang when executed. The only way out is a CPU reset.
One of the original and now most common means of application checkpointing was a "save state" feature in interactive applications, in which the user of the application could save the state of all variables and other data and either continue working or exit the application and restart the application and restore the saved state at a later time.
When debugging a concurrent and distributed system of systems, a bootloop (also called boot loop or boot-loop) is a diagnostic condition of an erroneous state that occurs on computing devices; when those devices repeatedly fail to complete the booting process and restart before a boot sequence is finished, a restart might prevent a user from ...
After the Linux kernel has booted, the /sbin/init program reads the /etc/inittab file to determine the behavior for each runlevel. Unless the user specifies another value as a kernel boot parameter , the system will attempt to enter (start) the default runlevel.
An Abnormal end or ABEND is an abnormal termination of software, or a program crash.Errors or crashes on the Novell NetWare network operating system are usually called ABENDs.
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
