Just to give you some feedback. Sometimes it takes a while until it crashes.
My hand made bisect is currently at two remaining patches:

de0f60ea94e132c858caa64a44b2012e1e8580b0
8b9fce77737ae9983f61ec56cd53f52fb738b2c7

reverting both solves my hard lockup. I will try to isolate the "bad" patch
but this takes some more days since I wont be in the "hazardous environment"
this week.
