vmcore-dmesg : Missing the log_buf symbol

[David Kahurani]

Hello,

I have generated a vmcore file using kdump and are now supposed to analyze
it.

First would be getting the dmesg logs from the core dump. This should be
done with:

          vmcore-dmesg vmcore

This however does not seem to work as there is the error:

    Missing the log_buf symbol

Could someone know how to get around this error?

Any help would be much appreciated.

Cheers,
David.
