Sorry - i thought for a moment that it was introduced by this recent 
change:

  7f8b7ed: kgdb: Always process the whole breakpoint list on activate or deactivate

but it's deeper than that indeed.

Basically we have two options:

 A- change kgdb to use the hw-breakpoints highlevel APIs (i'd prefer 
    that)

 B- or keep what we had so far: kgdb overrides existing GDB (and now 
    perf) breakpoints

I havent noticed that hw-breakpoints lock up under kgdb.
