https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D237590 --- Comment #1 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to Mark Millard from comment #0) I suppose that a possibility is that: A) It may be ddb related code that can not sleep some CPU(s) (because some already are sleeping?). B) It may be openfirmware tried to use an address that is invalid in the kernel on or after -r330610 . (A) may prevent seeing a notice that would point to (B) as a possibility, thus hiding the true cause. --=20 You are receiving this mail because: You are the assignee for the bug.=
