Apple have a nice Technical Note here:

which teaches one how to interpret the backtraces from kernel panic logs on
PowerPC, but no such document for Intel.
I have a panic log from an intel machine. I've made symbol files for the
"Kernel loadable modules in backtrace", but the backtrace is in the format:
Format - Frame : Return Address (4 potential args on stack)
e.g.
0x485ebc08 : 0x128d1f (0x3c9540 0x485ebc2c 0x131df4 0x0)
what do I plug into gdb to get the symbol name at that address? Everything
I've tried so far has resulted in this type of message:
(gdb) x/i 0x485ebc08
0x485ebc08: Cannot access memory at address 0x485ebc08
(gdb) x/i 0x128d1f
0x128d1f: Cannot access memory at address 0x128d1f
If you have the correct kernel debug kit mounted and loaded in gdb the
try "info line * 0x128d1f".
