Dynamode USB DSL modem 0572:cb00

    I'm having some small trouble with the subject modem.

    If I have cxacru compiled into the kernel and I do a reboot with the modem attached I get a kernel panic. If I have cxacru compiled as a module and I reboot, the kernel is fine.

    I plan to enable the kernel console so I can see further up the output.

    Any further suggestions for debugging would be appreciated.

      My idea about seeing the output further up didn't seem to work. I thought "earlyprintk=vga" would allow me to scroll up using "shift" and "page up", but it doesn't seem to work. Can somebody tell me how I might see the full output?

      Ok managed to get some output by using the "console as a printer" option in the kernel and adding "console=lp0" to my kernel arguments. It printed out quite nicely on my good ol' HP LJ6.

      Anyway I digress. Here is the actual error:-

      BUG: warning at lib/kref.c:32/kref_get()

      Call Trace:
      blah blah blah (I will post this if requested, I don't fancy copying it all out).

      Unable to handle kernel NULL pointer dereference at 0000000000000010 RIP:

      Oops: 0000 [1] SMP
      CPU 0

      Won't you please, please help me, help me ooohh ooohh ooh ooh ooooooooooooooooooh.

      I am going to try the kernel without SMP to see does that make any difference.

      Removing SMP from kernel made no difference anyway.
