    I'm trying to troubleshoot a Kernel Panic. It doesn't happen after a set series of events so it is hard for me to replicate. I have performed the Apple Hardware Test and have repeated it 5 times with no errors or faults found. I'm hoping maybe someone can help me decipher the panic log.

    Do you use dial-up internet?

    I was wondering about the com.apple.nke.ppp

    Having googled for it it seems a common cause of kernel panics. I guess it could also come up if you use xDSL broadband....

    The problem seems to be in a loadable device driver: com.apple.nke.ppp. This is (I think) a driver for the modem. Are you trying to connect over a dial-up connection? If you are not and disable the modem in the networking preferences does this go away?

    Not sure there's much you can do apart from leave feedback at Apple. It's a bug in Apple's PPP driver and it's up to them to fix it. Sucks, but there's not much else you can do but cross your fingers :(

    It's mentioned in quite afew places if you google for com.apple.nke.ppp.

    The reason it doesn't come up on the hardware test is that it isn't a hardware fault.
