I want to reiterate, I was on 4.12.13 when this problem started happening to me, and I haven't had a single BSOD since downgrading to 4.12.12, including during this entire bisect. It was happening frequently enough that if 4.12.13 wasn't at least one of the cuprits, I definitely would've had a few BSODs by now. -- You are receiving this mail because: You are watching the assignee of the bug.
