[-- Attachment #1 --] Rob: I did not remove Hans earlier patch, but your “latest” patch applied and compiled with no errors. I can now watch and control a TTY (v0) or a SSH session (pts/1) without crashing. Anything else you would like me to try? --mikej From: Rob Wing [mailto:rob.fx907@gmail.com] Sent: Monday, February 21, 2022 9:30 PM To: Michael Jung <mikej@paymentallianceintl.com> Cc: Hans Petter Selasky <hps@selasky.org>; freebsd-current <freebsd-current@freebsd.org> Subject: Re: New panic in main-n253273-a52d8d4a6c6: The previous attached patch should work for testing purposes, but it's incorrect if an error occurs. The fhold() should be below FILEDESC_SUNLOCK(), this patch addresses that.
