I've copied the tarce output of the kernel debugger, but unfortunately I don't have a crash dump, because I issued a ps command at the debugger prompt, and the debugger crashed, thus I couldn't type the panic command. Here's what we have: Fatal trap 9: general protection fault while in kernel mode instruction pointer =0x8:0xffffffff802bbc2b stack pointer =0x10:0xffffffff968e1fa0 frame pointer =0x10:0xffffffff968e1fb0 code segment =base 0x0, limit 0xfffff, type 0x1b =DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags =interrupt enabled, resume, IOPL=0 current process =931 (fetch) [ thread pid 931 tid 100090 ] Stopped at m_xhalf+0x3b: db> trace Tracing pid 931 tid 100090 td 0xffffff00114d1500 m_xhalf() at m_xhalf+0x3b bpf_filter() at bpf_filter+0x49f bpf_mtap() at bpf_mtap+0xcc nve_ifstart() at nve_ifstart+0x1fa ether_output_frame() at ether_output_frame+0x249 ip_output() at ip_output+0xb17 tcp_output() at tcp_output+0x9c2 tcp_usr_rcvd() at tcp_usr_rcvd+0x70 soreceive() at soreceive+0x1009 soo_read() at soo_read+0xc0 dofileread() at dofileread+0x94 kern_readr() at kern_readr+0x60 read() at read+0x4a syscall() at syscall+0x4b2 Xfast_syscall() at Xfast_syscall+0xa8 --- syscall (3, FreeBSD ELF64, read), rip = 0x800b0984c, rsp = 0x7fffffffe428, rbp = 0x400 --- My kernel config file is available at: http://tux.t-hosting.hu/DREAM >How-To-Repeat: Don't know.
