How to identify the thread ID or CPU ID that issued a printk() to the kernel ring buffer from a vmcore

Issue

• How to identify the thread ID (TID) or CPU ID that issued a printk() call to write messages to the kernel ring buffer (dmesg) from a vmcore.

• How to determine which thread accessed /dev/watchdog0, leading to watchdog timeout messages and a kernel panic:

[105351.966765] watchdog: watchdog0: watchdog did not stop!
[105351.966841] watchdog: watchdog0: watchdog did not stop!
[105373.209527] Kernel panic - not syncing: 06: An NMI occurred. Depending on your system the reason for the NMI is logged in any one of the following resources:
[105373.209531] 1. Integrated Management Log (IML)
[105373.209532] 2. OA Syslog
