Now, when this machine panics, I see: <stack trace> Waiting for remote debugger connection. Options..... Type ------------ ---- continue.... 'c' reboot...... 'r' enter kdb... 'k' However, I cannot seem to type anything on the "graphics" console. I was logged into the console at the time of the crash in text mode, via entering >console as the username; eg no windowing was running. Do I need to be running with a serial console? Or doing anything else differently? Or is it looking to talk kdb over the network? Yep, it's over the network. I think it might be possible to do it over serial but since I have 2 macs ethernet works for me (and I've not had to debug ethernet recently;-) Some debugging info is in the Developer Documentation, also found @ : http://www.opensource.apple.com/projects/documentation/howto/html/KEXT_Tutor... HelloDebugger.html -ej FWIW, the behaviour is the same (minus kdb) with the 1.4 kernel which ships with OS-X 10.1 BTW, does devfs_remove() work? I don't see any other code using it, and its where my current panic is happening (on the 5th call to it, out of 64 device nodes). Cheers, Drew
