https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233377 --- Comment #7 from Mark Johnston <markj@FreeBSD.org> --- (In reply to Sean Bruno from comment #6) Indeed, this points again at the UMA bucket zones. The stack is somewhat bogus; I believe the only way that we can call uma_zalloc() while freeing something is by allocating a bucket. I think the best approach will be to figure out why memguard-enabled kernels don't boot, and then use memguard to find the use-after-free. --=20 You are receiving this mail because: You are the assignee for the bug.=
