Here's a backtrace from a panic I had last night on a 3.0 box. It used to run -stable and has never panicked before AFAIR; I upgraded it to -current last week when I got it colocated. I suspect the panic was caused by overheating, since it doesn't make sense that it should panic in rename() and it was stuck between an ND Uniline 88/20 and a fridge (don't ask). OBTW, it's an Elf kernel. GDB is free software and you are welcome to distribute copies of it under certain conditions; type "show copying" to see the conditions.
