No other setting of kern.sched.* affected. I've introduced the setting by reading posts [1] and [2] on freebsd-current ML. Thanks for the hint, Jan! Andriy, I took time to bi-sect and determined the commit triggered this issue was e745d729be60. [3] Worked OK even with kern.sched.steal_thresh=0 at a342ecd326ee. [4] Tested commits are as below (tested order, not using git bisect): 0b79a76f8487: [Known to be OK] 8db1669959ce: [Problematic rev I first encountered] 0f6829488ef3: OK df8dd6025af8: OK 4f917847c903: OK e745d729be60: NG! bd84094a51c4: OK a342ecd326ee: OK Konstantin, no more chance to get into ddb on hang up until my previous post. ^T never worked on hang up situation. Sory. But does info above help?
