Frederic, can you please tell us > current status if you are tracking this issue?
Peter has a pending queue for .37 which includes:
[RFC][PATCH 3/7] perf, hw_breakpoint: Fix crash in hw_breakpoint creation
This patch should fix the issue (it depends on others in the queue).
What is mmotm1014 BTW? Because you should see this bug only in a tree that has tip:/perf/core merged inside, like linux-next.
Thanks.
