The thing is pretty much the same debug kernel config has been used for
a few years, so I don’t deliberately enable anything today.

The best bet is probably to skim through the “Kernel hacking” section of
the config and enable whatever you feel relevant if you have not enabled
already.

The cmdline is also in the .config via CONFIG_CMDLINE.

First, it comes with the dmesg that crashes and followed by the good dmesg
after reverting the commits (starting from line 644).
