This is an interesting report, though I cannot reproduce it. While running net-mgmt/fastnetmon using netmap(4) mode in a jail, the procstat(1) command works as intended. (In reply to Marek Zarychta from comment #1) Indeed, I cannot reproduce panic when process is running into a jail. I also get a panic using 14.2-BETA1 Can you get the vmcore from the panic? (In reply to Konstantin Belousov from comment #3) Here it is, full /boot/kernel (GENERIC-DEBUG) and /var/crash/vmcore file: https://drive.google.com/file/d/10SIvm6h1Z2YLPV5CCKxEh0ljtAuKizJr/view?usp=drive_link You posted kernel and vmcore, but not debugging symbols, which makes the archive not useful. Please either give me the kernel.full file exactly as was used to generate both kernel and vmcore from your archive, or I will ask you for the series of commands to execute in kgdb on your system with the core.

Mark OBJT_DEVICE that do fill cdev into the handle, with a new object flag OBJ_CDEVH.
