Hello, It seems that the Linux-compatible "scsi-generic" driver is not working in 12-stable when using multimedia/makemkv; it never finds a blu-ray player, which it does on 12.1. The change that seems to have done it is revision 361038 https://svnweb.freebsd.org/base/stable/12/sys/cam/scsi/scsi_sg.c If I use a scsi_sg.c from before that revision, everything works as in 12.1. I didn't have a chance to look any deeper to see which bit caused the problem and won't for some days. Makemkv is a linux binary-only application, so it is a black box as far as getting a backtrace usable backtrace as it also doesn't crash in searching for the device. Though I would happily take any pointers on how one would debug this. I actually noticed this in -CURRENT, but tested it quickly now in stable, and thought I should say something before 12.2 goes out. Should I also file a bugzilla report or is this sufficient? Best regards, -- Trenton
