It was useful. Are you sure your target is running the 32-bit kernel? What does uname -a print before you enter the kernel debugger. So, armed with this information, I invoked gdb correctly by doing: gdb /Volumes/KernelDebugKit/mach_kernel --arch=x86_64 and, now, showallkmods works. Yes, you need to have your kernel debug kit exactly match whatever build your target is running. There is no close enough. Will do - as soon as bugreport comes back up (appears to be down at the moment).

In this particular case the kernel didn't change between the builds (so it might kind of look like it works), but other content that contributes to the Kernel Debug Kit did change, so you might see strange behavior until you get it synchronized. I'd recommend using --arch=x86_64 at the start of your gdb invocation.

It can also help in cases where a debug session is interrupted and you need to get the panicked system to just reset its internal state machine. Brilliant. I was pretty sure I was running a 64-bit kernel and rechecked in the system profiler. In the entry for 64-bit Kernel and Extensions in the Software section, it said yes. Ok. So, unless I can locate the 10.6.8 10k549 kernel debug kit (which may not even exist), I will need to downgrade the machines to 10.6.7 10J869, which I can find at https://developer.apple.com/downloads...correct?
