Hi Adrian, I see bad fault a bit earlier: just after dozens of cycles of "init": at pc = 0x4001e4, but it cou What found by me: after page fault on file objects the page content is filled with small delay, i.e. it results in race. If you add small piece of work (black-hole-cpu) after fault (or context switch?), then the page is filled with data (magic). I want to find some time this weekend (tomorrow) to trace geom layer (ktrace?). Thanks!
