config VERBOSE_MCHECK
bool "Verbose Machine Checks"
config VERBOSE_MCHECK_ON
int "Verbose Printing Mode (0=off, 1=on, 2=all)"
depends on VERBOSE_MCHECK
default 1
---help---
This option allows the default printing mode to be set, and then
possibly overridden by a boot command argument.
For example, if one wanted the option of printing verbose
machine checks, but wanted the default to be as if verbose
machine check printing was turned off, then one would choose
the printing mode to be 0. Then, upon reboot, one could add
the boot command line "verbose_mcheck=1" to get the normal
verbose machine check printing, or "verbose_mcheck=2" to get
the maximum information available.
Take the default (1) unless you want more control or more info.
