Unfortunately (or not), the kernel on this system was built without symbols, witness, invariants, or debugger. So I built a new kernel with all of those things and...no more panics. Makes debug a bit difficult. I then built a new kernel without debugging and tried again. The panics resumed. The ONLY differences in the kernels were symbols, witness, invariants,and debugger. I can get a dump and I'll try building a kernel with symbols but no WITNESS or INVARIANTS and see if that crashes. In the mean time, has anyone else seen this? % mdconfig -a -t vnode -f /D/file.iso -u 1 % Do some stuff which may or may not involve the md device. I normally mount the device and later dismount it, but I have had panics without doing anything else. Panics often come very soon after I de-configure the device. (mdconfig -d -u 1) I'll submit a PR if I can get enough information to put something that looks useful. R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
