Description Mihail Stanciu 2014-10-16 07:39:50 UTC

As part of our automation efforts, we've recently added a battery of log tests on all boards.
We are unsure if the following message is valid for jasperforest. Please let us know if it can be safely ignored.

Comment 1 Darren Hart 2015-05-04 16:21:10 UTC

I am presuming this is related to the System.map file.

Cal, Please investigate the source of the message and compare with the constructed images.

Comment 2 California Sullivan 2015-05-07 23:03:37 UTC

I believe the cause of this is that klogd needs the System.map file to translate addresses into functions and variables, and the System.map file is only included if you use the dev kernel.

Comment 3 California Sullivan 2015-05-08 20:13:06 UTC

The System.map file is included in kernel-dev and fixes this error message.

Comment 4 Bogdan Alexandru Voiculescu 2015-11-16 09:06:06 UTC

verified per above comment; we are not testing jasperforest anymore.
