  2. HLT (x86 instruction) - Wikipedia

    en.wikipedia.org/wiki/HLT_(x86_instruction)

    In the x86 computer architecture, HLT (halt) is an assembly language instruction which halts the central processing unit (CPU) until the next external interrupt is fired. [1] Interrupts are signals sent by hardware devices to the CPU alerting it that an event occurred to which it should react.

  4. Signal (IPC) - Wikipedia

    en.wikipedia.org/wiki/Signal_(IPC)

    In Unix-like operating systems, this event automatically changes the processor context to start executing a kernel exception handler. In case of some exceptions, such as a page fault , the kernel has sufficient information to fully handle the event itself and resume the process's execution.

  5. Kernel panic - Wikipedia

    en.wikipedia.org/wiki/Kernel_panic

    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 ...

  6. Page fault - Wikipedia

    en.wikipedia.org/wiki/Page_fault

    The MMU detects the page fault, but the operating system's kernel handles the exception by making the required page accessible in the physical memory or denying an illegal memory access. Valid page faults are common and necessary to increase the amount of memory available to programs in any operating system that uses virtual memory , such as ...

  7. Machine-check exception - Wikipedia

    en.wikipedia.org/wiki/Machine-check_exception

    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:

  8. Interrupt flag - Wikipedia

    en.wikipedia.org/wiki/Interrupt_flag

    In systems that support privileged mode, only privileged applications (usually the OS kernel) may modify the Interrupt flag. In an x86 system this only applies to protected mode code (Real mode code may always modify the Interrupt flag). CLI and STI are privileged instructions, which cause a general protection fault if an unprivileged ...

  9. Linux kernel oops - Wikipedia

    en.wikipedia.org/wiki/Linux_kernel_oops

    After a system has experienced an oops, some internal resources may no longer be operational. Thus, even if the system appears to work correctly, undesirable side effects may have resulted from the active task being killed. A kernel oops often leads to a kernel panic when the system attempts to use resources that have been lost. Some kernels ...
