Bjorn and I discussed the need for such a "safe" mode feature when you

Can we please make it a config option the instead of adding code
to every kernel? Also maybe the bringup should be in the name
to make this more clear?
One other requirement was to have a runtime option rather than compile
time option.
When someone reported a problem, we wanted to be able to say "use this
option and see if system boots" without doing any bisects or
recompilation.
This would be the first step in troubleshooting a system to see if
fundamental features are working.
I don't mind changing the name
Bjorn mentioned safe option. I made it safemode. I am looking at Bjorn
for suggestions at this moment.
