https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293382 --- Comment #53 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Kyle Evans from comment #51) If you see my last debugging patch, my main suspicious place right now is bcopy(). The values of the fd as reported give quite huge size for bzero, and I suspect that this is the exceptionally large value for bcopy, if not unique. So I am trying to open-code bcopy() to see if memcpy_erms() might be to blame. It might be not bcopy() itself but a cpu bug with extra-large %rcx for rep;movsq for instance. Just speculating. (In reply to Paul from comment #52) This is fine. But SLIST_REMOVE() must deref NULL if the element is not found.
