https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217126 --- Comment #3 from tcovert+freebsd@sahuagin.net --- I will give it a go. I didn't see anything on the terminal, just found myse= lf at the boot screen. In my attempt to dd the image, I got 4.1GB out of 32GB and a "device not configured". My attempt to have the drive show up on my mac was unsuccessfu= l, while another SD card would show up fine. So, I'm now suspecting that there is a data corruption on the SD card. I do= n't think it should still be able to reboot my machine, but it may not be somet= hing that would be normally expected. I'm happy to help how I can.=20 I'll turn debug.debugger_on_panic=3D1 and see if I can gather a backtrace. = I'm referencing https://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-gdb.ht= ml in the hopes that it'll lead me correctly. FWIW, I've got encrypted swap and zfs underneath the system.=20 > sysctl debug.debugger_on_panic debug.debugger_on_panic: 1 Indicates that this was already set during my last 3 reboots. /var/crash only contains minfree --=20 You are receiving this mail because: You are on the CC list for the bug.=
