The problem still exists and is easy to reproduce. Compile/link/install a kernel with Tagged Command Queuing enabled. Try to make a backup using dump. After that your SCSI bus freezes. The one and last message you see from syslog: sd0(ahc0:0:0) Tagged openings reduced to 3. I have an AHA 2940 and IBM DORS 32160 SCSI DISKS. For backup I use a TDC 4222 5 GB QIC streamer. My system/kernel: FreeBSD-current as of yesterday. Kernel as of today. My kernel config file is in the attachement.
