Field Description
Thread Name and number of the kernel thread deadloop.
Context Context for the kernel thread deadloop.
Chassis Number of the IRF member device on which the kernel thread ran.
Slot
Slot number of the MPU on which the kernel thread ran. (Distributed
devices in IRF or standalone mode.)
ID of the IRF member device on which the kernel thread ran. (Centralized
devices in IRF mode.)
Fixed to 0 without any special meaning. (Centralized devices in standalone
mode.)
CPU ID Number of the CPU where the kernel thread ran.
Kernel module info
Information about kernel modules that had been loaded when the kernel
thread deadloop was detected, including kernel module name and memory
address.
Last 5 thread switches
Last five kernel thread switches on the CPU before the kernel thread
deadloop was detected, including kernel thread name and kernel thread
switching time with microsecond precision.

• Reg—Name of a register.
• Val—Value saved in a register.
Dump stack Stack information.
Call trace
Function call stack information, which shows the instruction address of a
called function at each level.
Instruction dump
