https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259458 --- Comment #13 from Andriy Gapon <avg@FreeBSD.org> --- (In reply to Andriy Gapon from comment #12) Applied the fix but still seeing variations of the crash. The data I see makes me think that somehow concurrent calls to iflib_fl_refill() for the same iflib_fl_t (free list) are happening. One hypothetical possibility is that iflib_stop/iflib_fl_setup are not sufficiently synchronized with the taskqueue threads (that call _task_fn_rx). I am not familiar with grouptask / taskqgroup code, but I do not see any drain-like calls. So, I wonder if there could be a race between an enqueued task and the stop/setup operations. -- You are receiving this mail because: You are the assignee for the bug.
