console grab with panic

Two new samsung EVO850 1TB ssds

geom_mirror mirror

newfs -U -O 2 -t -E -b 65536 -f 8192

It's perfectly fine to detach drives and destroy the mirror, but the panic is not ok given the circumstances.

Which revision was this? r302091 should have addressed this bug.
Comment 2 Poul-Henning Kamp freebsd_committer 2016-12-02 17:13:26 UTC
Sorry for not reporting that, the kernel is r298283M on this system.

I will try a newer kernel and report back.

I tried on a different machine, running 11.0-RELEASE-p2, and that didn't reproduce the problem.

It will be some days before I can try a new kernel on the original HW, will report back.

You're right, it seems to be fixed.
