Hmmm... Does the kernel completely boot-up? (As in a shell prompt) Does this occur when loading the shell? What libraries are you using? Where did you get those libraries or did you build them yourself? Or, is this occurring before the kernel is completely booted?

We see this on boot-up or shortly after. Could you shed some light on some situations where this may happen? Most other situations (unimplemented and illegal instructions, floating point, etc.) would cause the user_mode(regs) call to return a TRUE condition, but ours apparently returns a FALSE condition, thus the panic. Why does one get a software emulation exception with the PR bit of the MSR equal to 0? Any suggestions highly appreciated.
