CONFIG_BOOTPARAM_HUNG_TASK_PANIC: Number of hung tasks to trigger kernel panic

General informations

The Linux kernel configuration item CONFIG_BOOTPARAM_HUNG_TASK_PANIC has multiple definitions:

Number of hung tasks to trigger kernel panic found in lib/Kconfig.debug

The configuration item CONFIG_BOOTPARAM_HUNG_TASK_PANIC:

• prompt: Number of hung tasks to trigger kernel panic
• type: int
• depends on: CONFIG_DETECT_HUNG_TASK
• defined in lib/Kconfig.debug
• found in Linux kernels: 6.19-rc+HEAD

Help text

When set to a non-zero value, a kernel panic will be triggered if the number of hung tasks found during a single scan reaches this value.

The panic can be used in combination with panic_timeout, to cause the system to reboot automatically after a hung task has been detected. This feature is useful for high-availability systems that have uptime guarantees and where a hung tasks must be resolved ASAP.

Say N if unsure.

Say Y here to enable the kernel to panic on "hung tasks", which are bugs that cause the kernel to leave a task stuck in uninterruptible "D" state.
