It works = for a few seconds, then panics. The messages don't look too useful to = me, but here they are: Unread portion of the kernel message buffer: processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 3610 (kdm_greet) trap number =3D 12 panic: page fault cpuid =3D 0 (kgdb) bt #0 doadump (textdump=3Ddwarf2_read_address: Corrupted DWARF expression. ) at pcpu.h:224 #1 0xffffffff8087ef79 in kern_reboot (howto=3Ddwarf2_read_address: = Corrupted DWARF expression. ) at kern_shutdown.c:449 #2 0xffffffff8087f413 in panic (fmt=3Ddwarf2_read_address: Corrupted = DWARF expression. ) at kern_shutdown.c:637 #3 0xffffffff80b77d08 in trap_fatal (frame=3Ddwarf2_read_address: = Corrupted DWARF expression. ) at trap.c:852 #4 0xffffffff80b78012 in trap_pfault (frame=3Ddwarf2_read_address: = Corrupted DWARF expression. ) at trap.c:678 #5 0xffffffff80b777aa in trap (frame=3DVariable "frame" is not = available. ) at trap.c:456 #6 0xffffffff80b62142 in calltrap () at /tmp/exception-vH8hmc.s:179 #7 0xffffffff80b6f6b0 in pmap_enter (pmap=3Ddwarf2_read_address: = Corrupted DWARF expression. ) at pmap.c:3587 #8 0xffffffff80adafa0 in vm_fault_hold (map=3Ddwarf2_read_address: = Corrupted DWARF expression. ) at vm_fault.c:935 #9 0xffffffff80ad9787 in vm_fault (map=3DVariable "map" is not = available. ) at vm_fault.c:229 #10 0xffffffff80b77f26 in trap_pfault (frame=3Ddwarf2_read_address: = Corrupted DWARF expression. ) at trap.c:736 #11 0xffffffff80b77670 in trap (frame=3DVariable "frame" is not = available. ) at trap.c:358 #12 0xffffffff80b62142 in calltrap () at /tmp/exception-vH8hmc.s:179 #13 0x00000008040d7796 in ??
