Hi! how do I dump the text that a kernel panic show to a digital camera with usb? It could be a digital camera or a file, etc. I need to know the stack trace that cause the kernel panic.

I wonder if dmesg will show you the Kernel Panics..
of | Code: | | dmesg > textfile.txt |
to print it into a file.

No, it will not work because the system hungup, it freeze.
I tried to use kmsgdump without any luck. |

boot from a LiveCD and mount the HadDrive to check /var/log for your kernel panic

It will not work because the data of kernel panic (stack trace, register, variables, etc) get lost after reboot, you need to dump the kernel panic to a print or serial console |

Yes, this could but I still have the problem of getting the dump when a kernel panic occur.
