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 ...
This file contains a "snapshot" of useful low-level information about the system that can be used to debug the root cause of the problem and possibly other things in the background. If the user has enabled it, the system will also write an entry to the system event log.
Some operating systems, e.g., z/OS, have facilities for Reliability, availability and serviceability (RAS) and the OS can recover from the crash of a critical component, whether due to hardware failure, e.g., uncorrectable ECC error, or to software failure, e.g., a reference to an unassigned page.
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. For some systems, ECC and other correctable errors may be reported through MCE facilities. [5] Example:
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
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.
In OpenVMS, success is indicated by odd values and failure by even values. The value is a 32-bit integer with sub-fields: control bits, facility number, message number and severity. Severity values are divided between success (Success, Informational) and failure (Warning, Error, Fatal). [9]
Rarely an experienced user would reinstall Windows. In the case of the former, the boot loader will most likely inform the user the name of the missing file, allowing for the user to supply and/or reinstall the missing files to resolve the boot problem. In the case of the latter, however, the computer will not be able to boot, even into safe mode.
