config DEBUG_ERRORS
bool "Verbose kernel error messages"

help
This option controls verbose debugging information which can be
printed when the kernel detects an internal error. This debugging
information is useful to kernel hackers when tracking down problems,
but mostly meaningless to other people. It's safe to say Y unless
you are concerned with the code size or don't want to see these
messages.
