XK0-006 Practice Question: A Linux server experiences a kernel panic during…
A Linux server experiences a kernel panic during boot. You need to capture the panic message for analysis. Which kernel parameter should be added to the GRUB command line to ensure the panic message is displayed before the system halts?
⚠ Common exam trap
Test-takers frequently confuse `panic=` with a boot-time delay or a recovery mode option, mistakenly thinking `single` or `quiet` will help display the panic message, when in fact `panic=` is the specific parameter that controls the post-panic behavior to keep the message visible.

Correct answer & explanation
✓
panic=10
The `panic=<seconds>` kernel parameter instructs the kernel to wait the specified number of seconds after a kernel panic before automatically rebooting. By setting `panic=10`, the system pauses for 10 seconds, allowing the panic message to remain on the console for capture and analysis before the system halts or reboots. This is the correct parameter to ensure the panic output is visible.
