--- Comment #7 from Mark Johnston <ma...@freebsd.org> --- (In reply to Gregory Neil Shapiro from comment #5) Hmm, the fact that rsp is still close to a page boundary still suggests that a stack overflow's happening, but perhaps it's an instance of infinite recursion or so. For some reason we are not getting a stack trace. I'm not sure why, I think that should generally work in the face of double faults. Assuming you're running a release kernel, the other quick thing to try is a GENERIC kernel with debugging enabled. -- You are receiving this mail because: You are the assignee for the bug.
